我拥有 rwx 权限的文件的 Homebrew 权限被拒绝

Question

我有一个 2016 MacBook Pro（带触摸条）和 Mac OS Sierra (10.12.3)。我新安装了 Homebrew (v1.1.9) 和运行 brew install gcc49。它似乎可以很好地安装所有依赖项，但是一旦进入 gcc，我就会得到

Error: Permission denied - /Users/<me>/Library/Caches/Homebrew/gcc@4.9-4.9.3.tar.bz2

Homebrew 下载后的原始权限：

-rw-r--r--  1 <me>  <company_domain>    86M Jun 26  2015 /Users/<me>/Library/Caches/Homebrew/gcc@4.9-4.9.3.tar.bz2

我尝试设置为 755 并分组为 admin，但没有成功：

-rwxr-xr-x  1 <me>  admin    86M Jun 26  2015 /Users/<me>/Library/Caches/Homebrew/gcc@4.9-4.9.3.tar.bz2

> brew install gcc49

Error: Permission denied - /Users/<me>/Library/Caches/Homebrew/gcc@4.9-4.9.3.tar.bz2

然后我 chown 将目录设为组 admin 而不是公司域。它已经具有 775 权限。仍然没有运气。

我看过几篇帖子，其中人们必须 chown 目录才能使自制程序快乐，但我没有看到给定文件或目录的权限问题。

brew doctor 报告了一些意外的动态库、头文件和 .pc 文件。我不确定这些是否来自我公司的 Mac OS 图片。

我是不是忽略了一些明显的东西？感谢您的帮助。

这是完整的初始安装输出：

Answer 1

尝试 sudo chown -R <me>:admin /usr/local/* 然后重试。您可能需要递归地恢复某些用户或组的所有权（此命令将执行此操作）。
