Always the same error:

I guess something wrong with my ruby. But i don't know how to fix it

My environment:

MacOS 10.10.5
Xcode 7.2

Thanks in advance

回答1:

The system ruby installation seems to be messed up. Try removing the offending /Library/Ruby/Site/2.0.0/rubygems.rb (and may be more of enclosing folders)

Ruby have its bundled rubygems at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0 so it should work with these.

Once ruby is alive - you can try upgrading rubygems again by sudo gem update --system if needed, but I advise setting up a ruby version manager like rvm (rvm.io) and leave the system ruby be there only for emergences and backing the brew.
