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

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

也试试执行这个命令

Sudo chmod +t /tmp

首先,使用MacOS Catalina,不再允许更改/usr/local的所有权的基本方法。例如:

$ sudo chown -R "$USER":wheel /usr/local
Password:
chown: /usr/local: Operation not permitted
$ sudo chown -R "$USER" /usr/local
chown: /usr/local: Operation not permitted
$ sudo chown -R $(whoami) /usr/local
chown: /usr/local: Operation not permitted

因此,上面常用的答案不能使用。然而,其次,退一步说,如果主要考虑的是安装或升级Homebrew,而不是想要更改/usr/local本身的权限,那么更改/usr/local的权限可能会太过了(就像用大锤锤钉子一样)。它会影响您的整个机器和其他软件可能也在使用/usr/local。例如,我在/usr/local中有maven和mySQL相关的文件。

一个更精确的解决方案是按照Homebrew GitHub站点上给出的说明安装Homebrew,即

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

它将Homebrew安装在/usr/local中,而不改变/usr/local本身的所有权。相反,Cellar、Caskroom、Frameworks、Homebrew等都安装在/usr/local目录下。在我看来,这似乎是一个更优雅、更精确的解决方案。

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

在我的情况下,/usr/local/框架甚至不存在,所以我做了:

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

然后一切都按照预期进行。
