启动rails server时出错：警告：不安全的可写dir / usr在PATH中，模式040777
我正在关注Treehouse上的Ruby教程，并且在启动rails服务器时不断收到以下错误信息：
/usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777 /usr/local/rvm/gems/ruby-1.9.3-p392@global/gems/bundler-1.2.4/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777 我试图用sudo chmod ow / usr / local / fix和其他变体修复它，但是可悲的是，它没有为我做任何事情。
即使有这个错误，虽然服务器仍然会启动，一切都会正常工作，但现在我也得到了很多其他的错误，服务器甚至不会启动了，我想他们可能会连接？
这是我现在得到的错误：

任何build议，解决这个问题？ 我试图重新安装Rails，但没有帮助，仍然是相同的错误。
谢谢！
尝试从磁盘实用程序中select“修复磁盘权限”
[编辑]
对于OS X El Capitan：
sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /
尝试你的chmod -R （recursion）：
chmod -R ow /usr/local/
关于警告 ：
... warning: Insecure world writable dir /usr in PATH, mode 040777 ... warning: Insecure world writable dir /usr in PATH, mode 040777
他们告诉你目录/usr （而不是/usr/local ）是世界可写的。 修复： chmod -R go-w /usr 。
错误说：
... `load': /Users/yassine/treebook/app/models/user.rb:12: syntax error, unexpected keyword_end (SyntaxError)
你的user.rb文件的第12行有一个额外的关键字。
