Ruby on rails 从rvm迁移到rbenv后，gem注释不起作用

我可以通过执行

sudo gem install annotate

（由于权限被拒绝，我不得不使用sudo）来安装annotate。它似乎已安装，但运行时出错。我认为问题可能与卸载rvm有关。（现在使用rbenv）。安装rvm时，我删除了~/.rvm文件夹并删除了.bash_配置文件中的引用

无法以普通用户身份安装annotate

Chris-Muenchs-MacBook-Air:wifiwaiters cmuench$ gem install annotate
ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_sysopen - /Users/cmuench/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/annotate-2.6.5/AUTHORS.rdoc
Chris-Muenchs-MacBook-Air:wifiwaiters cmuench$ 

能够通过sudo安装

Chris-Muenchs-MacBook-Air:wifiwaiters cmuench$ sudo gem install annotate
Successfully installed annotate-2.6.5
Parsing documentation for annotate-2.6.5
Done installing documentation for annotate after 0 seconds
1 gem installed

苏多

通过以下操作修复：

sudo chmod -R 755 ~/.rbenv

现在我不需要使用sudo来安装gems并运行它们
