更新所有权限正确的文件/文件夹:

Compaudit | xargs chmod g-w

您不需要使用sudo更改所有者-除非文件属于root

(在macOS BigSur上测试)

一旦你了解了原因，解决方案是微不足道的和明确的。

原因:compaudit输出的目录有group或other写权限(world-writable);或者这些文件属于root或你自己以外的其他人。 例如:在我的案例中，compaudit给了我:

% compaudit 
There are insecure directories:
/usr/local/share/zsh/site-functions
/usr/local/share/zsh

如果我们列出这些文件/目录的权限(在本例中)

% ls -lh /usr/local/share 
total 0

现在我们很容易发现问题，不是吗?注意zsh/和zsh/site-functions目录与其他目录的区别… zsh不支持允许管理组修改它们的“w”。

解决方案:关闭组可写权限!

% chmod g-w /usr/local/share/zsh 
% chmod g-w /usr/local/share/zsh/site-functions 

就是这样!你可以出发了。打开一个新终端，你应该不会再看到“zsh compinit: insecure directories”消息了;)

上面列出的解决方案没有一个对我有效。相反，我最终卸载并重新安装了Homebrew，这很管用。卸载说明可以在这里找到:http://osxdaily.com/2018/08/12/how-uninstall-homebrew-mac/

这是我在https://github.com/zsh-users/zsh-completions/issues/433#issuecomment-600582607上唯一有用的东西。感谢https://github.com/malaquiasdev !

  $ cd /usr/local/share/
  $ sudo chmod -R 755 zsh
  $ sudo chown -R root:staff zsh

大多数答案都提供了解决方案，但没有提到为什么会出现这种警告。以下是ZSH公司的一段摘录:

For security reasons compinit also checks if the completion system would use files not owned by root or by the current user, or files in directories that are world- or group-writable or that are not owned by root or by the current user. If such files or directories are found, compinit will ask if the completion system should really be used. To avoid these tests and make all files found be used without asking, use the option -u, and to make compinit silently ignore all insecure files and directories use the option -i. This security check is skipped entirely when the -C option is given.

因此，解决方案意味着解决以下一个(或所有)问题:

将当前用户设置为所有目录/子目录/文件的所有者，原因如下: compaudit | xargs chown -R "$(whoami)" 删除组/others文件的写权限，原因如下: Compaudit | xargs chmod go-w

另一种方法是使用跳过这些检查

compinit -u

但我并不建议这样做，因为把问题藏在地毯下只能在短期内解决问题。

当我sudo -i启动根shell时，我得到了相同的警告，@chakrit的解决方案对我不起作用。

但我发现-u开关的compinit工作，例如在你的.zshrc/zshenv或你调用compinit的地方

compinit -u

注意:不建议用于生产系统
