多用户配置中的 Brew Doctor 警告

Question

我正在我计算机上的两个用户帐户上安装 RVM，为此我需要安装 Homebrew。我已成功安装 Homebrew，运行 brew doctor，然后在第一个帐户上安装 RVM 顺利。切换到第二个，Homebrew 已安装，但安装 RVM 时遇到此消息 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 会引发几个警告：

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

Warning: /usr/local/include isn't writable.

This can happen if you "sudo make install" software that isn't managed by

You should probably `chown` /usr/local/include

Warning: /usr/local/lib isn't writable.

You should probably `chown` /usr/local/lib

Warning: /usr/local/share isn't writable.

You should probably `chown` /usr/local/share

Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed

directories, then the install will fail during the link step.
You should probably `chown` them:

    /usr/local/share/man
    /usr/local/share/man/man1

Homebrew 不是为多用户帐户使用而设计的。所做的是控制 usr/local 将其所有权更改为安装它的用户。所以它适用于您的第一个用户（安装自制软件）但对第二个用户失败。

您可以找到替代安装说明来解决此问题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，并将组所有权授予 usr/local 可能会起作用。但是，这可能会产生一些奇怪的副作用。
