Question

我正在使用OSX 10.12，最近我遇到了一个奇怪的问题。如果我使用Homebrew安装包，则无法链接包，因为权限不正确。运行brew doctor后，我收到以下消息：

Warning: The following directories are not writable:
/usr/local/sbin

This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a formula tries to write a file to this directory, the
install will fail during the link step.

You should change the ownership and permissions of these directories.
back to your user account.
sudo chown -R $(whoami) /usr/local/sbin

运行了很多不同的权限命令，我在网上找到了我仍在努力解决这个问题。我尝试过（至少）以下命令

sudo chown -R $(whoami) /usr/local
sudo chown -R $(whoami) /usr/local/sbin
sudo chown -R "$USER":admin /usr/local
sudo chown -R "$USER":admin /Library/Caches/Homebrew

非使用过的突击队员在哪里工作。我在每个权限命令后尝试brew docter但似乎没有任何效果。然后我认为应该在usr / local目录中查看使用ls -la的权限。我注意到sbin文件夹是符号链接的。有关usr / local文件夹中的权限，请参阅下面的列表。不确定这是好还是不好？这可能是我的问题的原因，我怎么能解决这个问题？

drwxrwxr-x   16 myusername  staff   544 Oct 10 16:10 .

这是brew --config命令

这是符号链接的sbin文件夹的权限

drwxr-xr-x   246 root            wheel   8364 Aug  4 02:08 sbin

Answer 1

跑步brew doctor应该告诉你：

警告：以下目录不存在： / usr / local / sbin

只需运行：

sudo mkdir -p /usr/local/sbin

和：

sudo chown -R $(whoami) /usr/local/sbin

Answer 2

我在 Mac OS Big Sur (11.5.1) 上遇到了这个错误。我运行以下命令来修复它：

undefined

自制权限。 / usr / local / sbin不可写
