Rake 10.0.3在RVM中運行錯誤的Ruby版本

Question

我今天在基於RVM的應用上運行了bundle update rails，並且在此過程中將Rake更新爲10.0.3。現在我不能運行rake spec了，因爲它試圖使用系統Ruby而不是正確的RVM Ruby。

下面是輸出：

$ bundle exec rake spec -b 
/usr/local/lib/ruby -S rspec ./spec/controllers/articles_controller_spec.rb ... 
rake aborted! 
/usr/local/lib/ruby -S rspec ./spec/controllers/articles_controller_spec.rb ...

注意RSpec的試圖掏出來/usr/local/lib/ruby而不是到安裝RVM紅寶石正確的路徑。如果我只是在命令行中運行rspec，一切經過：

$ bundle exec rspec 
..................................... 

Finished in 1.81 seconds 
37 examples, 0 failures 

我降級到耙10.0.2，並沒有這個問題，我可以在其他用Rake 10.0.3複製它我的本地機器上的類似Ruby版本的應用程序。

這個問題似乎是Rake::TaskLib::RUBY定義錯誤：

$ bundle exec ruby -e 'require "rake/tasklib"; puts Rake::TaskLib::RUBY' 
/usr/local/lib/ruby 

任何想法有什麼錯我的環境？

OS X 10.8.2 
RVM 1.18.5

看起來你可以通過這個變化的影響https://github.com/jimweirich/rake/commit/968682759b3b65e42748cd2befb2ff3e982272d9#L0R9

確保取消設置變量：
