oh-my-zsh目录权限问题

问题

You have mail.
[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxrwx 7 hans admin 238 2 9 10:13 /usr/local/share/zsh
drwxrwxrwx 6 hans admin 204 10 1 2017 /usr/local/share/zsh/site-functions

[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.

刚开始的时候根本不知道是什么问题，后来在oh-my-zsh上查了下，发现竟然有人也有遇到此问题，虽然很久之前了。

https://github.com/robbyrussell/oh-my-zsh/issues/6835

在上面看到说执行下面命令就可以解决，但是对我好像没什么用。

chmod 755 /usr/local/share/zsh
chmod 755 /usr/local/share/zsh/site-functions

后面我就在.zhsrc中加入ZSH_DISABLE_COMPFIX=true，刚开始加入到最后一行发现根本不行，之后查看了下issues看到有人说必须添加到 第一行，然后就试了下，发现可以了。

至此问题就解决了。
