安裝Rails時出現rubygems.rb問題

Question

我最近不得不刪除Ruby中的所有版本並重新安裝它們。 這樣做之后（我現在使用的是2.0.0，如果那是相關的）我無法重新安裝rails。 這一切都是用RVM完成的。

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

更新：我嘗試重新安裝RVM，正如Albert建議的那樣。 我仍然收到相同的錯誤消息。

當我跑which -a ruby

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

當我運行rvm remove 2.0.0

這是一個問題，因為使用sudo （你不應該運行sudo ），修復它運行：

rvm fix-permissions

你現在應該能夠：

rvm reinstall 2.0.0

它將重新安裝你的紅寶石，確保一切正確設置，你的寶石可用於新的紅寶石。
