也试试执行这个命令

Sudo chmod +t /tmp

我在卡特琳娜，我得到了这个错误:

touch: /usr/local/Homebrew/.git/FETCH_HEAD: Permission denied
touch: /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/.git/FETCH_HEAD: Permission denied
fatal: Unable to create '/usr/local/Homebrew/.git/index.lock': Permission denied
fatal: Unable to create '/usr/local/Homebrew/.git/index.lock': Permission denied

我只需要把Homebrew目录翻个遍

sudo chown -R "$USER":admin /usr/local/Homebrew

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

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。

所有这些建议都可能奏效。在最新版本的brew doctor中，有了更好的建议。

首先-通过在命令行中运行这个命令来修复你可能已经造成的/usr/local混乱:

sudo chown -R root:wheel /usr/local

然后获取路径的所有权，应该专门为这个用户:

sudo chown -R $(whoami) /usr/local/lib /usr/local/sbin /usr/local/var /usr/local/Frameworks /usr/local/lib/pkgconfig /usr/local/share/locale

所有这些信息都是可用的，如果你运行sudo brew update，然后阅读所有的警告和错误，你会遇到…

我尝试了这页上的所有方法，最终使用了这个解决方案:

酿造卸载-强制酿造桶;取消$tap_name;酿造更新;啤酒清理;酿造桶清理;

我的情况与OP类似，但是我的问题是由使用酿造桶运行sudo引起的，然后让我的密码不正确。在此之后，我被阻止安装的权限所困扰。
