Looking for an existing zsh config...
Using the Oh My Zsh template file and adding it to ~/.zshrc.

         __                                     __

Please look over the ~/.zshrc file to select plugins, themes, and options.

成功之后，打开新的终端后，会显示一些信息（以前安装的时候，没有这玩意）：

[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxr-x  3 zhangli53  admin  96  4  8 12:12 /usr/local/share/zsh
drwxrwxr-x  2 zhangli53  admin  64  4  8 12:12 /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.

所以要把这个信息屏蔽掉：

vim ~/.zshrc

文件第一行加入：

ZSH_DISABLE_COMPFIX="true"    # 有引号

保存之后，再执行命令：

source ~/.zshrc   # 原封不动的执行这条命令就ok了，再开新终端就生效了
