在Linux Mint 17上安装Ruby on Rails

Question

I have been struggling this task. I have been developing in php but want to switch to ruby. My question is how do I install ruby on rails on Linux Mint 17.

Answer 1

After installing rvm, just type gem install rails and you are ready with rails.

For an IDE I think a popular choice is RubyMine and if you are into text editors you can try using Vim or another popular choice Sublime text editor .

I would recommend using editor in the beginning, just to get used to the terminal and all the ruby tools out there like rails , rake , rspec etc.

Answer 2

Simply put, to install ruby on rails on this OS. You should follow

Answer 3

I just installed ruby2.2 & rail4.2 on mint mate 17 via rvm & gem .

Steps:

• [install rvm]
• open vim
• \\curl -sSL https://get.rvm.io | bash -s stable
• reopen a vim
• rvm -v
• [install ruby]
• sudo apt-get purge ruby (this will remove old ruby that is not installed by rvm)
• rvm list known (this will show available ruby versions)
• rvm install 2.2.0 (it's quite smart, will do a lot check, might take a while)
• setup GEM_HOME, and choose ruby version via rvm use ruby-2.2.0 (I didn't use this way, for some reason)
• or, put ~/.rvm/rubies/ruby-2.2.0/bin to your PATH, by hand, (I use this way, because I have a common config file for such things)
• reboot or re-login or source some_file , (depends on your configuration)
• ruby -v
• [install rails]
• gem install rails (install to "current_ruby/bin/" inside rvm folder,)
• rails -v
• done

Issues

• When install rails, it might stuck at "Installing ri documentation for rails". Solution: just stop it, and execute gem install rails again. Or refer to A discussion on stackoverflow about this issue.
