I'm trying to deploy a Rails (4.2.6) application on a Windows 7 system (customer requirement).
I installed rubystack-2.2.5-3 and this comes with Ruby 2.2.0, but my app was developed using Ruby 2.3.1. I started thin server as explained in the deploy instructions and then tried to run my app, but got an error "Method does not exist" and as it is running perfectly in my Linux box, I assumed that it is because of the Ruby version.
I can't install RVM or RBENV on Windows, right? So I researched Google and saw there was a Ruby 2.3.0 installer. I downloaded it and installed it. Then I updated the PATH variable to point to my new Ruby installation. But when I do a bundle install it still complains that my Ruby version in Gemfile (2.3.0) is different from my installed Ruby.
How can I tell it to run the new Ruby?
Am I doing something wrong?
I am supposed to work on a quite antique Ruby On Rails project to make some minor (mostly HTML and CSS) changes on some webpages. I did not work with Ruby On Rails before and I am just getting into it.
I have cloned the project via git from github and installed all gems via 'bundler install'. Note that I am using an old version of Ruby (1.8.7) since I was told the project would not work with a newer version. Note also I am on Windows 7 and the project was built with Mac OS X.
Now I am trying to get the changes I made to the live site (after commiting and pushing the changes to the git repository) with Capistrano (Installed and Version 2.8.0) which should be possible with
bundle exec cap production deploy
However when I try this I just get:
bundler: not executable: cap
Any ideas what is going wrong here? Thanks alot in advance!
Kind regards,
Peter
Generally, capisrano is not defined as a gem in a project's Gemfile. Try installing the gem with gem install capistrano.
You can also check if Capistrano is installed on your system by running cap -T in your project folder. This should give you a list of all tasks in that project.
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!
I've installed Ruby on a Windows computer
After Setting Up Ruby Installer What Command line tools do you use?
http://railsinstaller.org/en
I've tried the command
rvm use 1.9.3
using the command prompt ruby and rails
I get the error message
rvm is not a recognised command
From RVM’s FAQ:
Does RVM work on windows? Will it in the future?
NO. If you would like to manage multiple versions of ruby on windows please use pik which is an excellent tool by Gordon Thiesfeld. You can find it on GitHub. There are plans to include windows support in RVM 2.0.
https://rvm.io/support/faq#does-rvm-work-on-windows-will-it-in-the-future
Doing Rails development on Windows is a little bit more of a challenge and you may run into some annoyances, but it's definitely possible.
Uru worked well for me as a nice alternative to RVM, which doesn't run on Windows. However, if you just want to have one version of Ruby installed on your computer and work with it, you don't even need to bother with Uru.
Windows is not the best environment to develop with Ruby ...
RVM doesn't work and PIK hasn't updated for more than 2 years..

This installer doesn't install RVM. It installs Ruby interpreter and Rails.
Since you've installed it, I assume you have your Ruby and libraries for it (called gems) rails and bundler. Execute gem list in your shell to verify (it should output a looong list).
Then you should create a new Rails project:
rails new project_name
...and then go into the folder that got created
cd project_name
bundle what you have:
bundle install
...and launch the server to see if it works:
rails server
or
rails s
You will likely run into issues with tzinfo gem if you're on 64-bit Windows, but that can be easily fixed by searching around StackOverflow, it's been discussed.
Gool luck to you. Developing Rails applications in Windows proved to be hard to me. Consider launching a virtual machine (using, for example, VirtualBox) with Linux aboard. That's what you could do in Linux:
install RVM as the site suggests:
curl -sSL https://get.rvm.io | bash -s stable
install the latest MRI available - feel free to replace ruby with the version you need, like rvm install 2.0.0
rvm install ruby
select and set as default the Ruby you need, you've tried a similar line apparently with Ruby 1.9.3
rvm --default use ruby
another long process
gem install rails
rails new project_name
(same as described above)
cd project_name
bundle install
rails s
That should work, and that's what you've probably seen. Again, I highly recommend using Linux in VirtualBox (or anything similar) for Rails development. A native Linux installation could only be a better environment, but most people are not ready for this just yet.
I am trying to follow this tutorial to AJAXfy file uploads in my Ruby on Rails 3 application. On "Step 6. Using iframes and responds_to_parent" chapter I have to install the 'responds_to_parent' plugin but I am not able.
I use a Mac OS running "Snow Leopard", so in my Terminal I enter this:
script/plugin install http://responds-to-parent.googlecode.com/svn/trunk/
but the response is:
-bash: script/plugin: No such file or directory
What I have to enter?
BTW: "what I have to do"/"how to handle" gem and plugins for the my RoR 3 application when I will deploy it on a hosting server?
script/plugin install is no longer in rails. Use this syntax instead:
rails plugin install
All the executables inside the script directory were consolidated into script/rails with the release of Rails 3.
As far as deploying goes, using rails plugin install will add the code to your /vendor/plugins directory, so as long as you check that into your source control system, it should deploy with the rest of your code. Gems should be included in the Gemfile. You will need to use "bundle install --deployment". If you are using capistrano, there is a recipe included with bundler.
