问题
when I try to use ruby with the terminal, nothing happens.
The last days I've used it and everything worked but it doesn't anymore.
I installed rvm and the 1.9.3 version of ruby.
It works when I launch a script with ruby myscript.rb, and I tried installing rails but when I type gem install rails I get an error:
/Users/romainberger/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4: warning: Insecure world writable dir /Users/romainberger/.rvm/gems/ruby-1.9.3-p194 in PATH, mode 040777
As there is no output I don't know where the problem comes from. Does anybody have an idea?
Thanks

And to launch ruby I just type ruby

To fix the gem warning use:
chmod -R go-w /Users/romainberger/.rvm/
It will recursively remove write right for group and others (keeps write for user).
