bin/bash: ruby command not found. Ruby not in sudo path

Question

I can't seem to run any code on ruby with any text editor. This error is returned when code is run

/bin/bash: ruby: command not found
[Finished in 0.0s with exit code 127]
[shell_cmd: ruby "/home/user/Resume/ruby/WebScraper/redditscrape.rb"]
[dir: /home/user/Resume/ruby/WebScraper]
[path: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/user/.rvm/bin]

I found a similar question on stackoverflow sudo: ruby: command not found after ssh

As user terdon explains it's caused by ruby not being in the sudo path. So I tried sudo-ing my type ruby but nothing happened. How do I fix this? Thanks in advance!

if this helps my type ruby is /home/user/.rvm/rubies/ruby-2.2.2/bin/ruby

and my echo path is

/home/user/.rvm/gems/ruby-2.2.2/bin:/home/user/.rvm/gems/ruby-2.2.2@global/bin:/home/user/.rvm/rubies/ruby-2.2.2/bin:/home/user/.rvm/bin:/usr/local/heroku/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Solution

I have faced the same issue and fumbled to find an answer. here is how I solved it.

• start the program with the following shibang line so that ubuntu knows it is a ruby file. #!/usr/bin/env ruby
• change the directory to where your code lives cd /home/User1/program
• make your file executable by running chmod +x your_program.rb
• type in the terminal ruby your_program.rb notice the text "ruby"

Do you need the 2.2.2 version? The ruby package on my 14.04 system is at 1.9.1, and puts ruby in /usr/bin.

edit your question and add the output of whoami; echo $PATH

@ubfan1your $PATH shows /bin/ruby is not in there. try adding it by issuing this command: export PATH=$PATH:$HOME/user/.rvm/rubies/ruby-2.2.2/bin/ruby

Any why? Any explanations please? :)

What's broken is something usually configured during installation. Perhaps a reinstallation will fix it. It's next in line to 'Have you tired turning it off and on again?'

I tried it and now I get a redirection forbidden error whenever I run my code.

You clearly have something wrong with the system. That is a simple remove and install command which had 0 impact on my system when I ran it just now. I suggest looking at your /bin/ folder, then /usr/bin/ to see if the Ruby app is actually present in the first place. There seems to be some useful info on how this is structured here: askubuntu.com/questions/27213/…
