new macbook - trying to run Rails, now I get “internal:gem_prelude>:1:in `require': cannot load such file — rubygems.rb (LoadError)”

Question

I bought a new Macbook Pro and used migration assistant to move from my old iMac.

When I try to run Rails or even bundle install, I get:

internal:gem_prelude>:1:in `require': cannot load such file -- rubygems.rb (LoadError)
from <internal:gem_prelude>:1:in `<compiled>'

I do get the following:

$ ruby -v
ruby 1.9.3p374 (2013-01-15 revision 38858) [x86_64-darwin12.2.0]

My user on the iMac was burtondav, on the Macbook Pro it is davidburton. I don't know if that's the cause.

Thanks for the help!

尝试浏览此处提供的信息http://docs.rubygems.org/read/chapter/3

Answer 2

You may try symlinking

ln -s /Users/davidburton /Users/burtondav

but a proper solution would be to reinstall ruby & rubygems.
