我在计算机上的两个用户帐户上安装RVM，我需要安装Homebrew。我已经成功安装了Homebrew，运行brew doctor，然后在第一个帐户上安装了RVM，没有任何障碍。切换到第二个，安装了Homebrew，但安装RVM符合此消息ERROR: '/usr/local/Cellar' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!。
在第二个帐户上运行brew doctor会出现几个警告：
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
Warning: /usr/local/etc isn't writable.
This can happen if you "sudo make install" software that isn't managed by
by Homebrew. If a formula tries to write a file to this directory, the
install will fail during the link step.
You should probably `chown` /usr/local/etc

Homebrew不适合多用户帐户使用。可以控制usr / local将其所有权更改为安装它的用户。所以它适用于你的第一个用户（安装了自制软件）但第二个用户失败了。
您可以找到其他安装说明来解决此here
您可以采取的另一种方法是在两个帐户之间共享usr / local的所有权，使两个用户成为同一组的成员，并且向usr / local提供组所有权可能有效。然而，这可能会产生一些奇怪的副作用。
