我已经卸载和安装了3次Homebrew,因为它似乎永远不允许我安装任何东西,因为它在大多数安装结束时拒绝我的权限。

作为一个例子,我将发布我目前面临的libjpeg下载场景。

我尝试安装libjpeg并获得:

$ brew install libjpeg
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/jpeg-8d.mountain_lion.bottle.1.tar.gz
Already downloaded: /Library/Caches/Homebrew/jpeg-8d.mountain_lion.bottle.1.tar.gz
==> Pouring jpeg-8d.mountain_lion.bottle.1.tar.gz
Warning: Could not link jpeg. Unlinking...
Error: The brew link step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link jpeg'
Error: Permission denied - /usr/local/opt/jpeg

'brew link jpeg'的结果

Error: Permission denied - /usr/local/opt/jpeg

这是我的酿酒医生读的

$ brew doctor
Warning: "config" scripts exist outside your system or Homebrew directories.
./configure scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run brew link on these:

jpeg

这个许可问题已经使它不可能使用酿造任何东西,我真的很感激任何建议。


当前回答

我可以通过在文件夹上使用chown解决这个问题:

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

此外,你(很可能)必须在/Library/Caches/Homebrew上做同样的事情:

sudo chown -R "$USER":admin /Library/Caches/Homebrew

显然,我之前用sudo改变了我在/usr/local上的文件夹权限, 从这里开始,所有带有brew的安装都被证明是成功的。

其他回答

对我来说,它在那之后起作用了

更改权限命令导致另一个错误

chown: /usr/local:不允许操作

在我的情况下,我有问题删除和重新安装SaltStack。

在运行:

ls -lah /usr/local/Cellar/salt/

我注意到群组主人是“员工”。(顺便说一下,我运行的是macOS Mojave 10.14.3版。)员工组可能与我的工作场所配置有关,但我真的不知道。无论如何,我保留了这个小组,以防止自己进一步破坏任何东西。

然后我跑了起来:

sudo chown -R "$USER":staff /usr/local/Cellar/salt/

在那之后,我成功地用这个命令删除了它(不是以root用户):

brew uninstall --force salt

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。

从得票最多的答案命令不工作的我。

它得到输出:

Chown: /usr/{my_username}dmin:非法用户名

这个命令工作正常(组/usr/local已经是admin):

sudo chown -R $USER /usr/local

对于多用户Mac来说,这对我来说是可行的:

sudo chown -R $(whoami):admin $(brew --prefix)/*
