我用这些命令解决了我的问题:

sudo mkdir /usr/local/Cellar
sudo mkdir /usr/local/opt
sudo chown -R $(whoami) /usr/local/Cellar
sudo chown -R $(whoami) /usr/local/opt

如果您没有最新的Homebrew:我在过去通过强制Homebrew以根用户身份运行来“修复”这个问题，这只能通过将Homebrew可执行文件的所有权更改为根用户来实现。在某种程度上，他们删除了这个功能。

我知道他们会给出很多警告，说它不应该以根目录运行，但算了吧，否则它就不能正常工作。

如果你想要一个比毯子chown -R更有针对性的方法，你可能会发现这个fix-homebrew脚本很有用:

#!/bin/sh

[ -e `which brew` ] || {
    echo Homebrew doesn\'t appear to be installed.
    exit -1
}

BREW_ROOT="`dirname $(dirname $(which brew))`"
BREW_GROUP=admin
BREW_DIRS=".git bin sbin Library Cellar share etc lib opt CONTRIBUTING.md README.md SUPPORTERS.md"

echo "This script will recursively update the group on the following paths"
echo "to the '${BREW_GROUP}' group and make them group writable:"
echo ""

for dir in $BREW_DIRS ; do {
    [ -e "$BREW_ROOT/$dir" ] && echo "    $BREW_ROOT/$dir "
} ; done

echo ""
echo "It will also stash (and clean) any changes that are currently in the homebrew repo, so that you have a fresh blank-slate."
echo ""

read -p 'Press any key to continue or CTRL-C to abort.'

echo "You may be asked below for your login password."
echo ""

# Non-recursively update the root brew path.
echo Updating "$BREW_ROOT" . . .
sudo chgrp "$BREW_GROUP" "$BREW_ROOT"
sudo chmod g+w "$BREW_ROOT"

# Recursively update the other paths.
for dir in $BREW_DIRS ; do {
    [ -e "$BREW_ROOT/$dir" ] && (
        echo Recursively updating "$BREW_ROOT/$dir" . . .
        sudo chmod -R g+w "$BREW_ROOT/$dir"
        sudo chgrp -R "$BREW_GROUP" "$BREW_ROOT/$dir"
    )
} ; done

# Non-distructively move any git crud out of the way
echo Stashing changes in "$BREW_ROOT" . . .
cd $BREW_ROOT
git add .
git stash
git clean -d -f Library

echo Finished.

它不会对用户执行chmod操作，而是将homebrew使用的/usr/local中特定目录的写权限授予管理组(您可能属于该组)。它还会在执行之前准确地告诉你它打算做什么。

我不想浪费文件夹权限，所以我做了以下工作:

酿造的医生 酿造升级 啤酒清理

然后我能够继续安装我的其他酿造公式成功。

github上有一个杀手级脚本，可以修复/usr/local和brew目录上的烫发，使任何“admin”组的成员都可以访问。

https://gist.github.com/jaibeee/9a4ea6aa9d428bc77925

这是一个比选择的答案更好的解决方案，因为如果你把/usr/local/___目录改为$USER，那么你就破坏了那台机器上任何其他homebrew的管理用户。

以下是我发布这篇文章时脚本的核心内容:

chgrp -R admin /usr/local
chmod -R g+w /usr/local

chgrp -R admin /Library/Caches/Homebrew
chmod -R g+w /Library/Caches/Homebrew

chgrp -R admin /opt/homebrew-cask
chmod -R g+w /opt/homebrew-cask

其实很简单，执行这个命令: 酿造的医生

它会告诉你该怎么做，来修复权限问题，比如我的例子:

这就是问题所在:

Warning: The following directories are not writable by your user:
/usr/local/share/man/man5
/usr/local/share/man/man7

这就是解决方案:

You should change the ownership of these directories to your user.
  sudo chown -R $(whoami) /usr/local/share/man/man5 /usr/local/share/man/man7
