sudo -s 命令 [oh-my-zsh] 报错

运行sudo -s 命令时，[oh-my-zsh] 冒出下面一大堆提示：

[oh-my-zsh] Insecure completion-dependent directories detected:

[oh-my-zsh] For safety, we will not load completions from these directories until
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
[oh-my-zsh] See the above list for directories with group or other writability.

[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh]     compaudit | xargs chmod g-w,o-w

[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

　　

解决方案如下：

问题的描述中，其实已经给了我们解决方法：

[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh]     compaudit | xargs chmod g-w,o-w

[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

　　大意为：

要修复权限，可以通过禁用“group”和“others”的写入权限并确保这些目录的所有者是root用户或当前用户来修复权限。
以下命令可能有所帮助：
compaudit | xargs chmod g-w，o-w
如果上面没有帮助，或者你想跳过不安全目录的验证，你可以在你的zshrc文件中找到oh-my-zsh之前将变量ZSH_DISABLE_COMPFIX设置为“true”。

第一种：修改相关文件夹权限

为以上提示的文件夹修改权限（根据具体提示修改）

chmod 755 /Users/duke/.oh-my-zsh
chmod 755 /Users/duke/.oh-my-zsh/plugins
chmod 755 /Users/duke/.oh-my-zsh/plugins/git
chmod 755 /usr/local/share/zsh/site-functions
chmod 755 /usr/local/share/zsh/site-functions/_brew
chmod 755 /usr/local/share/zsh/site-functions/_brew_cask
chmod 755 /usr/local/share/zsh/site-functions/_git

第二种：设置变量 ZSH_DISABLE_COMPFIX=true

1. 在.zshrc文件的第一行添加 ZSH_DISABLE_COMPFIX=true
2. 运行source ~/.zshrc，重新加载.zshrc文件
