如何修复自制权限? [英] How to fix homebrew permissions?

问题描述

我现在已经卸载和安装了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都会拒绝我的权限.

I have uninstalled and installed Homebrew 3 times now because it seems to never allow me to install anything as it denies me permissions at the end of most installations.

作为一个例子，我将发布我目前面临的这个libjpeg下载方案.

As an example I will post this libjpeg download scenario that I'm currently facing.

我尝试安装libjpeg并获取:

I try to install libjpeg and get:

$ 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"导致

'brew link jpeg' results in

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

这是我的酿酒医生读到的

Here is what my brew doctor reads

$ 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

这个许可问题使它无法在任何东西上使用brew，我真的很感谢任何建议.

This permission issue has been making it impossible to use brew on anything and I would really appreciate any suggestions.

推荐答案

我能够通过在文件夹上使用chown来解决问题:

I was able to solve the problem by using chown on the folder:

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

此外，您(很有可能)必须在/Library/Caches/Homebrew上执行相同的操作:

Also you'll (most probably) have to do the same on /Library/Caches/Homebrew:

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

很明显，我以前使用sudo的方式更改了/usr/local上的文件夹权限， 从现在开始，事实证明，所有带有brew的安装都是成功的.

Apparently I had used sudo before in a way that altered my folder permission on /usr/local, from here on forward all installations with brew have proven to be successful.
