安装Rails时出现rubygems.rb问题

Question

我最近不得不删除Ruby中的所有版本并重新安装它们.这样做之后(我现在使用的是2.0.0,如果那是相关的)我无法重新安装rails.这一切都是用RVM完成的.

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

更新:我尝试重新安装RVM,正如Albert建议的那样.我仍然收到相同的错误消息.

我跑的时候 which -a ruby

/Users/bob/.rvm/rubies/ruby-2.0.0-p353/bin/ruby
/usr/bin/ruby

我跑的时候 rvm remove 2.0.0

这是一个问题,因为使用sudo(你不应该运行sudo),修复它运行:

rvm fix-permissions

你现在应该能够:

rvm reinstall 2.0.0

它将重新安装你的红宝石,确保一切正确设置,你的宝石可用于新的红宝石.
