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

I'm trying to initialize a new rails app on windows, and running rails new <appname> generates everything up to vendor/assets/stylesheets/.keep, but when bundle install is run, rails generates this error:
Checksum of /versions does not match the checksum provided by server! Something is wrong.
I'm not sure what's causing this, as I've done nothing to rails itself. Any help is appreciated.
Edit: If it's an error caused by windows being finicky, I have the option of moving to Linux, but I'd like to know what's wrong first.
I had the same issue using windows, and was able to solve it by uninstalling bundler and installing an older version.
rails new <appname>
gem uninstall bundler
gem install bundler -v 1.9
cd <appname>
bundle install
That did it for me!
In my case there was a *.pre.1 version and I chose to uninstall that particular version and then "bundle install" worked.
Try removing your ruby cache folder and then try again. So for example if you are on Linux machine and you are using rbenv and say ruby 2.1.5 folder. Your path would be similar to something like (Not sure where on windows ruby is stored):
~/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/cache/
Removing this folder and trying bundle install again should resolve the issue.
It will be great, if you move to a Linux machine.
On windows it's a hell to pay in my 5 years of experience what i have learned is not to mess with (ror) or (rs) in windows. here's a cheeky thing you can do an easy way. I believe you are using github as repo, as a editor you are using sublime if thats is a case open your gemfile you will see check the image or
try to clear cache on your server or update the gems.
I had this same exact error and solved it the following way. I think you are missing the ruby DevKit being installed.
Go here http://rubyinstaller.org/downloads/ and download/install the latest 32-bit Ruby version (as of writing this 2.2.4, you will need it for the web-console gem)
Make sure to add your ruby\bin folder to your environmental path variable
The trick is hidden near the bottom-left of the same page under the "Development Kit" section. You need to download and extract the right one into a permanent location (as of writing this for 32-bit - DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe)
After extracting the files, go into the main directory and run "ruby dk.rb init" followed by "ruby dk.rb install" (More information can be found here
That fixed it for me and i can now fully install with no checksum issues
This problem began when i tried to run my app. I wrote rails s and the console said me Could not find sdoc-0.4.1 in any of the sources Run bundle install to install missing gems. Then i wrote bundle install and the message that appeared was Checksum of /versions does not match the checksum provided by server! Something is wrong.
I solve this problem following this steps:
Wrote bundle install
The console said me Could not find sdoc-0.4.1 in any of the sources
Then i reinstalled this gem with gem install sdoc -v 0.4.1
I tried again to write rails s and it's was solved.

I removed the previous version of ruby I installed, ruby 1.9.1 to be precise, on my Ubuntu, and installed version 2.2.3. When I try to run bundle install on my terminal, I get this error
bash: /usr/local/bin/bundle: /usr/bin/ruby1.9.1: bad interpreter: No such file or directory.
Can anyone advice on how to fix it?
How did you remove the old version of Ruby?
It looks like it left the binary executable for bundler, so I'm guessing you just straight up deleted the usr/bin/ruby folder? Ruby installations (and most installations) tend to create executable binaries in other folders that need to be deleted as well.
I would highly recommend that you use something like rvm or rbenv to manage multiple versions of ruby on your system. Those tools are designed to do that sort of thing and are basically industry standard at this point.
My personal recommendation is rvm, although either is really fine. If you choose to go with that, check out rvm.io for installation instructions.
It'll install rvm with the latest ruby version. In addition to that you are free to install any other version of ruby or patch that you prefer, and you can easily switch between the two using rvm use <ruby version>
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.
This is a beginner-level question.
I'm using Ubuntu 12.04
I copied a project (created on Rails 4 using the rails new command) from Dropbox to my local environment, where I have previously install Rails 4 and up-to-date Ruby and RVM, went to project's directory, typed rails server and got
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
I ran gem install rails instead.
Will I have to run gem install rails on every project's directory? I thought the Rails install was a general and accessible on my whole environment.
The project was created using the same Ruby version, but on a MacOS X system.
The project is a static web brochure and has no database configuration.
Thank you in advance.
Make sure you're using the correct version of Ruby - the same version that you'd installed Rails into - with rvm list.
You likely have two of them (since you have such an issue) - the system Ruby and the RVM-installed Ruby. And likely RVM didn't engage and hook up the correct path to the rails executable, thus the error.
This should fix the issue:
rvm use whatever-ruby-you-had-installed-rails-into
Where whatever-ruby-you-had-installed-rails-into is a string like ruby-2.1.0-p0 taken from the rvm list output.
To make RVM retain Ruby version for the project.
echo whatever-ruby-you-had-installed-into >.ruby-version
in your project's path.
So after a few hours of testing, reproducing the problem, and reading (the other answers inclusive) I got the solution as follows:
Short answer: No. Rails needs to be installed only once.
Long answer: This problem occurred because of a default setting on Terminal that prevents the system from using RVM installations of ruby and rails. The solution is to integrate RVM with gnome-terminal as described in the RVM website.
With terminal window active, go to the menu at the top bar
Edit > Profile Preferences > Title and Command tab
Check the Run command as a login shell box
Restart Terminal and make sure your gemset and ruby version are set
rails server should now work as expected (you might be prompted to run bundle install before Rails can actually run fine, follow the promtp).
I am still learning to work with Ruby on Rails, so any inputs, clarifications, or additional information on the issue is more than welcome.
You don't have to install Rails on every project, but the gems that you need for that project.
With bundle install you install all the gems that you specify in Gemfile.
If you want to avoid reinstall the gems every time you change project, I suggest you to have a better look to RVM: it has got an opt called gemset (https://rvm.io/gemsets), if you use it you just need to switch your gemset:
rvm gemset use yourgemset
I hope it can help you.
On a VPS I tried to install Ruby. Because of memory exhaustion problems, we were unable to compile ruby 1.9.2 , and we decided to give Ruby Enterprise Edition a try. This compiled without complaining about memory problems.
Next, we install rubygems, and to test that it's working, I installed haml. It worked.
The next step was to install rails, via gem install rails. The version it downloaded was the latest, 3.0.5. Installation went ok. However, when I try to create a new project, I receive:
no such file to load -- rails/cli
Looking around on the internet, people said this is a problem related to older versions of rails, and some of them suggested to do a gem clean. I didn't have any other version of ruby before, therefore, no other version of rails. But, just to be sure, I did a gem clean and then reinstalled rails. The problem persists.
How can I fix this?
Make sure your running the gem binary that Ruby Enterprise Edition installed. So rather than:
gem install rails
it would be something like:
sudo /opt/ruby-enterprise-X.X.X/bin/gem install rails
To save having to type the whole path each time, you can symlink the REE binaries with something like:
sudo ln -sf /opt/ruby-enterprise-X.X.X/bin/* /usr/bin/.
