在M1上工作过

ProductName:    macOS
ProductVersion: 11.1
BuildVersion:   20C69

% compaudit
/opt/homebrew/share

将组权限从775更改为755

% sudo chmod 755 /opt/homebrew/share

drwxr-xr-x   33 xenea  admin   1056 Feb  2 01:28 share

这适用于我的Mac，因为High Sierra更新。

取消组写权限:

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

最好将更改限制在zsh目录中。

接受的答案在macOs Sierra(10.12.1)上不适用。必须从/usr/local递归吗

cd /usr/local
sudo chown -R <your-username>:<your-group-name> *

注意:你可以用whoami获取你的用户名，用id -g获取你的组

我尝试了张贴的每一个解决方案，最后没有一个适合我的特殊情况。然而，我想向那些向我指出所有权是多账户真正问题的用户表示感谢，而不是模式。 我把这个答案发布给其他有类似设置的人(M1 +两个账户+ /opt/homebrew/share)。

下面是我的设置:

我有一台M1，运行macOS Monterey 12.0.1，使用Homebrew。

我有两个帐户，一个管理员和一个普通用户(需要分开工作)。 我只有在普通用户上有不安全的目录问题，两个用户使用相同的自制设置，以下目录和文件受到问题的影响:

/opt/homebrew/completions/zsh/_brew
/opt/homebrew/share/zsh
/opt/homebrew/share/zsh/site-functions
/opt/homebrew/share/zsh/site-functions/_brew
/opt/homebrew/share/zsh/site-functions/_brew_services
/opt/homebrew/share/zsh/site-functions/_cargo
/opt/homebrew/share/zsh/site-functions/_gh
/opt/homebrew/share/zsh/site-functions/_git
/opt/homebrew/share/zsh/site-functions/_j
/opt/homebrew/share/zsh/site-functions/_lf
/opt/homebrew/share/zsh/site-functions/_task
/opt/homebrew/share/zsh/site-functions/_tldr
/opt/homebrew/share/zsh/site-functions/_vifm

改变模式没有任何作用，最终解决问题的方法是将每个问题文件和目录的所有权更改为root:admin，如下所示:

sudo chown root:admin /opt/homebrew/share/zsh/site-functions/*

最初，在问题出现之前，我的管理员用户拥有所有的东西，因此所有权看起来像这样:usr:admin

这是站点功能目录现在的样子，没有问题:

lrwxr-xr-x  1 root admin  30 Jul 19 19:41 _brew ->../../../completions/zsh/_brew
lrwxr-xr-x  1 root admin  79 Aug 10 20:26 _brew_services -> ../../../Library/Taps/homebrew/homebrew-services/completions/zsh/_brew_services

lrwxr-xr-x  1 root admin  57 Nov  6 16:28 _task -> ../../../Cellar/task/2.6.1/share/zsh/site-functions/_task
lrwxr-xr-x  1 root admin  57 Nov 18 01:45 _tldr -> ../../../Cellar/tldr/1.4.2/share/zsh/site-functions/_tldr
lrwxr-xr-x  1 root admin  56 Oct 13 11:11 _vifm -> ../../../Cellar/vifm/0.12/share/zsh/site-functions/_vifm

我得到这个问题在过去的5个月尝试了一些事情，但没有工作。最后帮助我的是这个。获取不安全目录的列表，然后按照下面的描述设置所有这些目录的chmod。

CLI# compaudit
There are insecure directories:
/usr/local/share/zsh
CLI# sudo chmod -R 755 /usr/local/share/zsh
Password:

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。
