mac 下的brew的权限问题

摘要: mac brew doctor 安装路径的权限

近日准备着手研究学习react，在用brew自检的时候，提示了路径的权限的问题

Warning: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.

You should probably change the ownership and permissions of /usr/local
back to your user account.

估计是近段时间安装的开发软件有点多。造成了本地路径的用户组的变更。出现了上面的冲突

直接走命令即可：

sudo chowm `whoami` /usr/local/

当然，对于brew，还是得经常的：

brew update && brew upgrade
