解決Mac經過 brew 安裝報錯的問題

在 mac 上 經過 brew 安裝 nginx 時候

brew install nginx

出現錯誤

Error: The following directories are not writable by your user:

/usr/local/share/man/man8

  

You should change the ownership of these directories to your user.

 sudo chown -R $(whoami) /usr/local/share/man/man8

  

And make sure that your user has write permission.

 chmod u+w /usr/local/share/man/man8

能夠經過一下方法來解決權限問題

終端輸入

sudo chown -R \`whoami\`:admin /usr/local/bin

　　sudo chown -R \`whoami\`:admin /usr/local/share
