如何修复自制程序的权限?

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:

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

我有这个问题… 一个可行的解决方案是更改/usr/local的所有权将root用户改为当前用户:

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

但实际上这不是一个正确的方法。主要是当您的机器是服务器或多用户时。

我的建议是像上面一样改变所有权，做任何你想用Brew实现的事情。更新，安装…等等)，然后将所有权重置回根:

  sudo chown -R root:admin /usr/local

这将解决问题，并保持所有权设置在适当的集合。

其他回答

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。

我使用了这两个命令并解决了我的问题

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

sudo chown -R $(whoami) /usr/local/etc/bash_completion.d /usr/local/lib/python3.7/site-packages /usr/local/share/aclocal /usr/local/share/locale /usr/local/share/man/man7 /usr/local/share/man/man8 /usr/local/share/zsh /usr/local/share/zsh/site-functions /usr/local/var/homebrew/locks

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

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。
