lando-macbook:rubygems-1.3.7 lando$ which ruby
/opt/local/bin/ruby

Answer 1

问题是你在/ opt / local / bin中有一个ruby可执行文件，可能在某些时候由macports安装。删除此ruby可执行文件或从PATH变量中删除/ opt / local / bin应该可以解决您的问题。 gems正在告诉你它找到ruby及其相关可执行文件的确切位置：

RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
  - EXECUTABLE DIRECTORY: /usr/bin
