我正在使用 OSX 10.12，最近遇到了一个奇怪的问题。如果我使用 Homebrew 安装包，则无法链接该包，因为权限不正确。运行后brew doctor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
在运行我在网上找到的许多不同的权限命令后，我仍然在努力解决这个问题。我尝试了(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
非使用过的突击队在哪里工作。我试过
brew docter在每个权限命令之后，但似乎没有任何效果。然后我认为它应该使用 ls -la 查看权限在 usr/local 目录中。我注意到 sbin 文件夹是符号链接(symbolic link)的。请参阅下面的列表了解我在 usr/local 文件夹中的权限。不知道这个好不好？？这可能是我的问题的原因吗？我该如何解决这个问题？drwxrwxr-x 16 myusername staff 544 Oct 10 16:10 .

这是符号链接(symbolic link)的 sbin 文件夹的权限

最佳答案
运行brew doctor应该告诉你:
Warning: The following directories do not exist: /usr/local/sbin
赶紧跑:
sudo mkdir -p /usr/local/sbin
和:
sudo chown -R $(whoami) /usr/local/sbin
关于permissions - Homebrew 权限。/usr/local/sbin 不可写，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46670727/
