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

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。

其他回答

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。

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。

对于多用户Mac来说,这对我来说是可行的:

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

对于像我一样降落在这里的人来说,第一选择是,按照这个建议去做:

brew doctor

这是最安全的方法,除此之外,它还建议我:

sudo chown -R $(whoami) /usr/local

这解决了权限问题。

OP这样做了,但显然没有得到上述建议;你可能会,从这里开始总是更好的,然后再寻找非平凡解如果它没有帮助的话。

我没有/usr/local/Frameworks文件夹,所以这为我修复了它

sudo mkdir -p /usr/local/Frameworks
sudo chown -R $(whoami) /usr/local/Frameworks

第一行为homebrew (brew)创建了一个新的Frameworks文件夹。 第二行为该文件夹提供当前用户权限,这就足够了。

常用命令如下:

Mkdir -创建目录[-p没有错误,如果存在,根据需要创建父目录] chown -更改文件所有者和组[- r对文件和目录进行递归操作] 打印有效的用户id

我有OSX High Sierra
