rails 3, why I can't use command line at ubuntu?

StackOverflow https://stackoverflow.com/questions/9474791

Question

I am running RubyMine 4 on Ubuntu 11.10, every thing is fine inside RubyMine, I can run the server, develop, etc .. but, when I need to work on the command line, I just can't do anything ..

I cd to my app directory, then I tried to: 

$ rails s

I get:

The program 'rails' is currently not installed.  You can install it by typing:
sudo apt-get install rails

That's is strange, how come its not installed, while I can work normally in RubyMine IDE !

I needed to use command line to uninstall a gem, to discover that I can't use the command line as it should ..

sam@ubuntu:~/Documents/RoR/course_builder$ gem uninstall 'capybara-firebug'
ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d capybara-firebug`

$ gem list -d will give me:

*** LOCAL GEMS ***

no gems there ..

if I type :

$ bundle install

I get:

/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError)
    from /usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11:in `require'
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11
    from /usr/bin/bundle:4:in `require'
    from /usr/bin/bundle:4

although bundle install inside RubyMine works fine

so, what I am missing here ?!! why I can't use the command line .. ?

here is my gem environment:

if I type ruby -v

sam@ubuntu:~/Documents/RoR/course_builder$ ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
Was it helpful?

Solution

I don't believe your rvm has been setup correctly. For sake of simplicity, let's start from the beginning following the instructions here:

http://beginrescueend.com/rvm/install/

Install in command line.

user$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

Open your .bashrc folder in your home directory.

user$ vim .bashrc

Edit and add:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

Source your .bashrc file and close the terminal

user$ source ~/.bashrc
user$ exit

Reopen terminal and check if rvm is working.

user$ type rvm | head -1

If it returns 

rvm is a function

We're good. Check if you have all of the prerequisites:

rvm requirements

Install as necessary. Pick your favorite flavor of ruby (it seems like it is 1.8.7, if so follow the exact command or replace it with your choice).

rvm install 1.8.7

When its done,

rvm use 1.8.7 --default

If this didn't work, please update post by running

which ruby

OTHER TIPS

Try running /bin/bash --login in your command line before doing any rails-related stuff. If it works, do this again in each new command line you open.
