I had rails working fine for several weeks but I tried to install PostgreSQL to match Heroku and it failed to work. Now, when I open the terminal it pretend rails is not there and sets the default ruby to 1.8.7. When I start RVM it finds the right version of ruby and finds rails again and can start the server but each time I open a new shell it's back to not finding anything. Plus, the git commands don't work even after starting rvm.
I have set rvm to start by default but that doesn't work either, it has to be started manually, and it still doesn't fix the git issue.
More Detail
I am installing on Mountain Lion. This already has Postgres but the tutorial I was using suggested installing fresh using Homebrew. The trouble was the Homebrew installation installs to /usr/local/var/postgres and the installed ppstgres installs to usr/var/postgres. The system automatically uses the usr/var/postgres version, so following the tutorial I chnaged the order of usr/local/bin and usr/bin in etc/paths. That didn't help so I changed it back. Everything then went to hell so I reinstalled Mountain Lion but nothing had changed.
There are two known problems with loading RVM & default ruby:
login shell: go to terminal emulator preferences and enable login shell, sometimes it might be required to use /bin/bash --login instead.
ZSH (+ Oh-My-ZSH): go to ~/.zshrc and comment out any lines starting with: PATH= or path=(, it is still possible to use those but they need to reference itself like: PATH=$PATH:HOME/.rvm/bin or path+=( $HOME/.rvm/bin ) - which update and not reset PATH. This might be a bug in terminal emulator or ZSH ...
The git issue is explained by the reinstall of Mountain Lion which did not automatically install the command line tools. That now works. The only pain is having to load rvm every time now.

I get the error:
Cannot start debugger. Gem 'ruby-debug-ide' isn't installed or its executable script 'rdebug-ide' doesn't exist.
but all gems were successfuly installed:
gem 'ruby-debug-ide'
gem 'debase'
I can run 'rdebug-ide' manually:
$ rdebug-ide
Using ruby-debug-base 0.2.1
Usage: rdebug-ide is supposed to be called from RDT, NetBeans, RubyMine, or
the IntelliJ IDEA Ruby plugin. The command line interface to
ruby-debug is rdebug.
But when I start debugging, RubyMine asks to install the ruby-debug-ide gem. Why?
And, after installation I get:
Cannot start debugger. Gem 'ruby-debug-ide' isn't installed or its executable script 'rdebug-ide' doesn't exist.
I'm running Mac OS X 10.11.3.
Here's the actual command that worked for me:
gem install ruby-debug-ide --pre

In your terminal you're probably not running the same ruby version as inside Ruby Mine. You can check this
In Ruby Mine
Preferences --> Laguanges and Frameworks --> Ruby SDK and Gems
In Terminal
$ ruby -v
If you're not running the same version, try to set RubyMine to use the same Ruby version that you're running in your terminal. This should solve the problem. Than, if you really want to use another RubyVersion, you will need to go to your terminal, change the Ruby version and manually install both gems
I have faced this issue when debugging in a docker-compose environment. I suspect that RubyMine does not refresh the list of available gem after the SDK is added.
So if you add the SDK then add ruby-debug-ide to Gemfile you will get the error.
Instead, (re)create the SDK after adding ruby-debug-ide.
I started getting this after upgrading from 2017.x to 2018.1. In my case, it seems that RubyMine needed a newer version but its error message implied it couldn't find any version and failed to install it. I think it was trying to install it with a different SDK.
Manually installing the latest ruby-debugger-ide (in my case the --pre flag was necessary) and then restarting RubyMine did the trick for me.
Since you're using Mac OSX, I couldn't provide the same exact answer for you, but you can find a similar way of achieving this. I'm using Ubuntu with Vagrant, so you may need to adapt it just a little bit.
Copy the following gem from RubyMine/rb/gems app folder, please copy the gem related to your ruby runtime and platform, there are different gems for different ruby runtime and platforms, in my case, its:
debase-0.3.0.beta7.gem
ruby-debug-ide-0.8.0.beta6.gem
Install them inside your app host, in my case its vagrant, in your case it could be inside your container, or in your host OS using the following command:
gem install --force --local *.gem
Set breakpoint and start debugging.
It may asks you one more time to install the gem, but then the debug will works for sure.
This worked for me
gem install debase-ruby_core_source
Source: Cannot install Rubymine Debugger
You should look into RubyMine settings, which ruby version and which gemset (global/default) it is using. Check out where these required gems are installed and make sure RubyMine is using that gemset where these are installed successfully.
I fixed this after viewing the responses here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/206072049-Cannot-start-debugger
The solution at the bottom suggested 'removing all my gems. removing ruby. cleaning up directories and rvm. removing ruby mine, then reinstalling everything'
I started with the easiest of these, which was to reinstall rubymine. That solved it for me.
I had this issue on Windows 11 running Ubuntu on WSL2. To solve, I manually copied the relevant files in my %AppData% directory into the corresponding directory in Ubuntu.
I found all the data at:
C:\Users[USER]\AppData\Local\JetBrains\RubyMine[VERSION]\ruby_stubs\[NUMBER]\home\[USER]\.gem\ruby\2.7.0
These files were copied to: \\wsl.localhost\Ubuntu\home\[USER]\.gem\ruby\2.7.0
After doing this, everything worked again.
I have faced this issue too with Rubymine 8, rvm 1.29.1 and Ruby version 2.3.3 And upgrading the Rubymine version from Rubymine 8 to Rubymine 2016.3 or latest resolves the issue for me.
Check ruby SDK's version is right.You can first using rails installer to install everything .
Then using gem to install rdebug for ruby 2+.
Make sure Rubymine's Ruby version is same to which you have installed.With those all done,you will be able to debug ruby.
Please check x286 vs 64 version, both Ruby and Rmine version. I had this problem runnin x86 rubyMine on 64 ruby
A combination of matching the host ide ruby version with the remote SDK version worked for me but required a few additional steps. I too am running mac os as my host (running mohave)
the remote environment setup in preferences -> ruby sdk and gems must have the same version as the remote target, including any gems installed.
NOTE: I had to re-install the bundler gem on both host and remote host to get the gem manager to install things auto-majically.
the project environment must be changed to use the same version as the remote host as well. this is in File -> preferences for new projects -> ruby sdk and gems.
NOTE: I also had to set the default RVM on my local host and remote host and unset the previous version as default in the local host preferences.
Once I did this I was able to get gems in sync and remote debugger to connect.
My solution was to go to Rubymine settings, to the available SDKs,
remove the SDK, restart Rubymine and add the SDK again.
Running Ubuntu 18 something, RubyMine version 2020.3. Had this issue. None of these suggestions worked for me, same error no matter what did. I was using RVM, and ruby 2.6 and 2.7, switched back and forth a cleaning and reinstalling gems along thew way, both debase and ruby-debug-ide were installed according to the gem list. Settings in rubymine matched "ruby -v" from the command line. VSCode worked perfectly with this setup.
In the end i removed RVM and all the ruby versions, installed ruby via rbenv, installed ruby 2.6.5 and that worked like a charm.
I think this error is generated for multiple reasons with no real way to figure out which reason for your specific instance. I would like to encourage jetbrains to generate more debug information on errors like this, or if you are generating error information, point out where it is when this happens.
Try these steps:
1. /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2. brew install ruby
3. echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
if you get unshallow error on any step then first try:
1. git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
2. git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow
3. /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
4. brew install ruby
5. echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
Lastly restart the terminal and check .bash_profile:
- nano ~/.bash_profile
If you see the path variable, just close it. Otherwise it means something went wrong :/.
The last step is to open
RubyMine -> Preferences -> Language and Frameworks -> Ruby SDK and Gems -> select the newest ruby version and apply.
You may need to update ruby version from the gemfile.
And it should be done!
Running OSX Mavericks, ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0], rvm 1.25.23 (master), and rails-4.1.0 (allegedly)
I'm working through the railsapps.org book on learning rails and made it about 1/2 way through yesterday. When I stopped for the day, I closed out iTerm2 and shut off the Macbook Pro. Today, I powered up, opened iTerm, navigated to my working directory (~/rubyonrails/learn-ruby) and entered rails -v.
I see this:
`Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.`
So I run sudo gem install rails and it shows that it has installed rails-4.1.0. Now rails -v still gives me the same error message above.
I tried also running rvm use ruby-2.1.1#learn-rails first and I still get the error message.
So I'm a little stuck and I can't figure out what to do to get rails working. Also, how do I go about setting up the bash environment such that I don't have to go through this each time? It would be nice to nav to my working directory and just start work without having to do a bunch of re-installation and reconfiguration each time.
Regards,
Jeff
please type in your shell:
$ bash --login
and then repeat your commands.
rails -v
Also try to call it with the full path:
like:
/your/path/to/rails -v
I think that the shell just doesn't know where rvm/rails etc is located.
You can solve this by entering:
$ source ~/.rvm/scripts/rvm
When you switch to the ruby-2.1.1#learn-rails ruby/gemset combo, and do gem list, what do you see?
The way people usually use rvm is to have every project folder specify the ruby & gemset it uses (they don't all have to be different). This is done with files called .ruby-version and .ruby-gemset. These should contain, in your case, ruby-2.1.1 and learn-rails respectively.
Set these if you haven't already, then leave the folder and enter it again. Then do bundle install to install the gems for the project into the rvm/gemset combo.
Your problem is that you ran
sudo gem install rails
The error message telling you to do this comes from your system Ruby, which doesn't know that you want to use RVM.
RVM installs gems into your user-space directory. By using sudo, you're bypassing this and installing it into (effectively) the superuser space, i.e. globally.
If you instead just run
gem install rails
then you'll be using RVM's copy of the gem utility rather than the globally installed version.
I was running PostgreSQL 9.1, installed from Postgres (/Library/PostgreSQL/9.1) - ie not homebrew etc and on Mac OSX Leopard.
I upgraded to Snow Leopard and then immediately to Mountain Lion and had a mass of problems with gems failing to build etc, but got them fixed
Rails server crashed on startup with pg issues & I tried everything I could find but could not fix the prob - fixes included links etc, which may still persist (hence this background info might inform the solution)
I uninstalled postgresql 9.1 and installed Postgres App
Now on rake db:create I get the following:
rake aborted!

I'm running rvm (as u can see) and after the OS upgrade created a new gemset and installed Ruby
I've changed my path to reflect the advice of Postgresql App, after the OS upgrade I installed Xcode 5 and the command line tools as advised and I think my database.yaml file is ok
I suspect the problem might be connected with sym-links made earlier in the process, but I'm stuck to find the solution
Sounds like something has gone wrong in your Ruby installation. Try reinstalling Ruby Enterprise Edition via RVM:
rvm reinstall ree
I was experiencing the same issue with a different version of libpq. What I ended up doing is creating a link to the correct file:
sudo ln -s /Applications/Postgres93.app/Contents/MacOS/lib/libpq.5.6.dylib /usr/local/lib/
My previous answer was deleted as it wasn't originally an answer, just a confirmation of a similar issue. Hope this helps!
In the end I think this was tied up with the fact that Mountain Lion ships with Postgresql rather than MySQL as per previous OSX versions.
I couldn't make sense of the Postgres App, so I uninstalled it and also uninstalled the version of Postgresql that shipped with ML and then did a Homebrew install of the latest version of Postgresql (which places it in a different place than if you install it direct from the Postgresql site).
This seemed to straighten everything up
So here is what happened:
I started working for a company and was given a macbook pro for work. I do customer support for Exceptional/Airbrake so i need to learn Ruby/Rails. So the laptop had a previous owner and i dont know what he did with it.
I tried to install Ruby and Rails and kept getting errors, then tried doing it with rvm, and i thought it was working as i could run irb and even execute a test program with ruby. I got tired of seeing the previous owners name on the command line so i changed the home folder and I am pretty sure this is where things got bad. I took the contents of rvm and everything and moved it to my User file from the old one then deleted the old one.
Everything seemed to still be working fine, but when I wanted to start working with rails as well, t it wouldnt work.So i figured i would just uninstall everything and start over, i tried rvm implode and removed all gems. when i run 'gem list', i get empty, and i cant find ruby anywhere but when i run irb, it still works. so i tried re-installing using rvm, but i keep getting errors.
The first error that occurs is:
No binary rubies available for: osx/10.7/x86_64/ruby-2.0.0-p0.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
the second error is:
Error running 'env GEM_PATH=/Users/robertmroz/.rvm/gems/ruby-2.0.0-p0:/Users/robertmroz/.rvm/gems/ruby-2.0.0-p0#global:/Users/robertmroz/.rvm/gems/ruby-2.0.0-p0:/Users/robertmroz/.rvm/gems/ruby-2.0.0-p0#global GEM_HOME=/Users/robertmroz/.rvm/gems/ruby-2.0.0-p0 /Users/robertmroz/.rvm/rubies/ruby-2.0.0-p0/bin/ruby /Users/robertmroz/.rvm/src/rubygems-2.0.3/setup.rb', please read /Users/robertmroz/.rvm/log/ruby-2.0.0-p0/rubygems.install.log
and the last error is:
ERROR: Loading command: install (LoadError)
cannot load such file -- openssl
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
I have gone through dozens of google searches, most of them leading me here, on each of these errors, and sometimes the certain error seems to be fixed, but in the end i cant get it to work. Should i just wipe the OS and start over, cause I have been trying to get this done for days now.
BTW, i dont know why it is installing 2.0.0 i thought rvm installed the latest version by default.
Before you blow out the system I'd:
Uninstall rvm (rvm implode, gem uninstall rvm) see this question
You should be left with just the base ruby. That should be the only one left.
Re-install rvm (\curl -L https://get.rvm.io without Rails).
Install the ruby version you want with rvm (rvm install 1.9.2) stay away from 2.0 for now.
Make sure your ruby version is installed and selected.
Install the rails version you want.
Hopefully that will straighten things out.
I also suffered from the same problems while installing Ruby , but after googling a lot I found the solution . Follow the below process :
If you have already installed anything uninstall all of that using Revo installer or by some other means , else go to step 2.
Next go to http://rubyinstaller.org/ and press the download button .
You will find a list of ruby versions , click on the latest version ( If you are running a 64 bit machine install the link with (x-64) else install the one without brackets .
Accept all the defaults and tick all the check boxes after downloading and setting it up , it will install in C:\ with name Ruby22 ( depending on its version )
Go to start menu type cmd , the use the command "cd C:\" without brackets , it will take you the C:\ drive
Check ruby -v , you should get the version number , else repeat the above process again .
Now use the command "gem install rails" , it will install all the rails requirements , this takes a lot of time .
Now use the command "gem install webrick" to install the web server
Now go to some browser , visit http://rubyinstaller.org/downloads/ , download the DevKit at the bottom of the page and extract it to some folder ( ex in C:\DevKit after creating the DevKit folder in C:\ )
Use the following commands in the same order
"ruby dk.rb init"
"ruby dk.rb install"
"gem install rdiscount --platform=ruby"
Rails is installed now .
Create a folder in C:\ for creating your rails apps and name the folder ( ex Rails _Apps ) use the command cd C:\Rails_apps to go there and use the command "rails new sample_rails_app" to create a Rails app with the name "sample_rails_app" .
It does a bunch of things and you are now able to use Ruby on Rails.
Ruby 2.0.0-p0 was recently released, so that is the latest version technically, although I kind of doubt you really want the latest version since it is so new and your company may still be running an older version like 1.9.3. Have you tried installing 1.9.3-p392 (the current 1.9.3 version)?
If you still get the error with 1.9.3, I would try the instructions shown on the RVM site:
$ rvm pkg install openssl
$ rvm reinstall 1.9.2 --with-openssl-dir=$rvm_path/usr
Rails and all my gem files + homebrew installs have been working fine up until this point.
I ran
homebrew install postgresql
and was following the prompts pretty much as indicated in this video but it kept giving me error messages saying there is a server already running. I checked
which psql
in the terminal and it reported a
usr/bin
location rather than
usr/local/bin
indicating I was using the postgres that comes with osx not the new homebrew install.
When I attempted to start the database server I recieved an error message saying the server is already running. There is a mention of this error message in the postgres help documentation but no real working solution.
Attempting brew doctor confirmed that i needed to change my PATH in .bash_profile.
I came across this little snippet here on stack overflow for the .bash_profile edit.
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin
I saved the file and managed to get postgres up and running fine but then when I went to start a new rails app.
rails new blog -d postgresql
it says
Rails is not currently installed on this system. To get the latest version,
simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
Any attempt to install does not work until i change the bash_profile file back to what it was before.
If I change it back postgres has the same issue again saying there is already a server running.
Also I thought it might be a launch agent or something but I don't think there are any that are set up.
I figure either something is installed in the wrong place or I have to add something to the .bash_profile?
Don't set your $PATH explicitly. You should append or prepend to it instead:
# In your .bash_profile
export PATH="/usr/local/bin:$PATH"
My guess is that you either use RVM or rbenv. If you change your path to /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/local/bin explicitly then RVM or rbenv won't be in your path.
