RVM Command: source ~/.rvm/scripts/rvm

问题:

I'm going through the rails by example tutorial series. I'm trying my best to find solutions prior to asking questions, so if I have missed anything I apologise.

Every time I need to boot up RVM from the command line in terminal I need to punch a command so that RVM initialises: source ~/.rvm/scripts/rvm

Is this normal? It seems that I cant get the RVM commands to work unless I punch in this code prior. Note I only have to enter the command once, not every time I need to enter an RVM command.

Many thanks for your help.

Put this in your ~/.profile or ~/.bashrc:

# This loads RVM into a shell session.
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"

So you don't have to manually type it for every session.

Further Tip

If you want to use gnome terminal (comes as standard in Ubuntu) with rvm, you can do the following:

• Edit the default profile. Check the following setting:

  "Run command as a login shell"
  

• This will stop loading the standard .bashrc by default. Fix this by making a soft link of .rvmrc pointing at .bashrc in your home directory

  cd
  ln -s .bashrc .rvmrc

Try closing terminal & then re-opening it to install a specific version of ruby:

For example) I typed in "curl -L https://get.rvm.io | bash -s stable --ruby"

Then I quit terminal & reopened terminal & typed in "rvm install 2.2.3" & it worked :D :)
