Specifying Rails Version

Question

I decided to upgrade to Ruby 2.0.0 and Rails 4.0.0. I\'m trying to set these as my default programs, by using this line:

rvm use 2.0.0@rails-4.0.0 --default         


        

Answer 1

You need to make a gemset first:

rvm --default use 2.0.0
rvm gemset create rails-4.0.0
rvm use 2.0.0@rails-4.0.0 --default
gem install rails

I think that is right.

Answer 2

most likely it is not empty, there is a lot of UTF-8 characters that editor will not show you, just remove the file before continuing:

rm -f /Users/michaeldunnegan/.gemrc
