问题
I had to downgrade Rails and now the gems, the versions, and everything, are completely messed up and I feel like jumping from my window.
I just want to destroy everything related with RVM, Ruby and gems to make sure I make a 100% clean reinstallation.
How can I do that?
回答1:
Linux and installed as regular user ? Than all you need to do is:
rm -Rf ./.rvm
rm -Rf ./.gem
rm -f ./.gemrc
You can also check ~/.bashrc and ~/.bash_profile files for lines like this:
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
This should be enough. If you've installed it in some custom way then try this:
$ rvm list # to see what version you have installed
$ rvm gemdir # to see where are gemfiles located
There is something like rvm remove as well but, if you want to just remove all, than it's not very interesting I think.
回答2:
If you have installed everything via rvm a simple
rvm implode
will remove all traces of rvm including rubies and gems. Even (as far as I remember, I'm not testing it right now) the shell files are updated.
回答3:
rvm implode which removes all ruby installations rvm manages, everything in ~/.rvm
