Ruby 没有在 mac os x 上启动

Question

当我尝试在终端上使用 ruby​​ 时，没有任何反应。 最后几天我用过它，一切正常，但现在不行了。 我安装了 rvm 和 1.9.3 版本的 ruby​​。 当我使用ruby myscript.rb 启动脚本时它可以工作，并且我尝试安装rails 但是当我输入gem install rails 时出现错误： /Users/romainberger/.rvm/rubies/ruby-1.9.3-p194/bin/gem:4: warning: Insecure world writable dir /Users/romainberger/.rvm/gems/ruby-1.9.3-p194 in PATH, mode 040777

由于没有输出，我不知道问题出在哪里。有人有想法吗？

谢谢

要启动 ruby​​，我只需输入 ruby

修复 gem 警告使用：

chmod -R go-w /Users/romainberger/.rvm/

它将递归删除组和其他人的写入权限（继续为用户写入）。
