Where on Ubuntu is Rails?

rubyonrails-talk

I followed the setup instructions for a fresh install of Mint15 according to this excellent tutorial : http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/ which sets up via rvm. I followed the instructions therein, but when I am in my ~ directory, i get:

user@Mint15Mate64 ~ $ rails create test The program ‘rails’ can be found in the following packages:

  • rails
  • ruby-railties-3.2 Try: sudo apt-get install

Oddly, if I also simply try:

user@Mint15Mate64 ~ $ rake -T rake aborted! No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb) /home/user/.rvm/gems/ruby-2.0.0-p247/bin/ruby_executable_hooks:15:in eval' /home/user/.rvm/gems/ruby-2.0.0-p247/bin/ruby_executable_hooks:15:in ’ (See full trace by running task with --trace)

Something is not appearing in my path – but I dont know what the entry shuld be in my path. My path appears as:

user@Mint15Mate64 ~ $ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/user/.rvm/bin

and if I do gem list I get: rails (4.0.0) railties (4.0.0) (among many other gems)

Can someone please point me in the right direction so that I can invoke

rails create test

please?

Thanks, RVic

Note that this shows the correct path. Have you got a file in your home folder .bash_profile. If so, what is in it? Also did you remember the step in the tutorial where it says to run ~/.bash_profile

Colin,

~/bash_profile has only the following line:

[[ -s “$HOME/.rvm/scripts/rvm” ]] && source “$HOME/.rvm/scripts/rvm” # Load RVM into a shell session as a function

when I reload bash profile: . ~/.bash_profile

rails works – it’s recognized by the. I have since rebooted since installing everything (I reloaded .bash_profile befoe the reboot). Must I reload .bash_profile every time? I thoughtthis was loaded whenever I opened a terminal window?

Thanks so much for your help in getting this going! RVic

You should not have to do it each time. I am not sure why it might not be invoking it automatically. If you add the line in .bash_profile to the file .bashrc then it should work ok. I don't think that it will matter that it is in .bash_profile also, but if you get any error messages when logging in or opening a terminal then remove .bash_profile (or rename it initially).
