homebrew - 如何修复 brew doctor 错误？

Question

对于这一切，我还是个新手，所以请原谅我的无能。

当我运行brew Doctor时，我得到以下信息。有人可以帮忙吗？

[/usr/local]$ brew doctor

Error: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Error: Some keg-only formula are linked into the Cellar.
Linking a keg-only formula, such as gettext, into the cellar with
brew link f will cause other formulae to detect them during the
./configure step. This may cause problems when compiling those
other formulae.

Binaries provided by keg-only formulae may override system binaries
with other strange results.

You may wish to brew unlink these brews:

libxml2

Directories in your path should not end in a slash. This can break other
doctor checks. The following directories should be edited:
/usr/local/git/bin/
[/usr/local]$

Error: Setting DYLD_LIBRARY_PATH can break dynamic linking. You should probably unset it. Error: Some keg-only formula are linked into the Cellar.

这要求您取消设置动态加载库路径。您可以通过找出设置它的位置并将其删除来完成此操作。最有可能的是，您的 ~/.bashrc 或 ~/.bash_profile 中有一行看起来像 export DYLD_LIBRARY_PATH=/some/path:$DYLD_LIBRARY_PATH

You may wish to brew unlink these brews:

libxml2

当 Brew 链接时，它会创建一个安装的符号链接(symbolic link)。这就是你如何拥有python2.6。 python2.7 已安装，但 python 将运行其中之一。

brew 取消链接 libxml2

这些是其他安装的残留文件。您可以删除它们。

rm 文件名

Error: You have uncommitted modifications to Homebrew's core. Unless you know what you are doing, you should run: cd /usr/local && git reset --hard 

这里，它告诉您您对 Homebrew 文件进行了修改。幸运的是，Homebrew 存储在 Git 版本控制中，因此您可以恢复这些更改。

cd/usr/local && git reset --hard

Error: Some directories in your path end in a slash. Directories in your path should not end in a slash. This can break other doctor checks. The following directories should be edited: /usr/local/git/bin/ 

PATH 变量是您在命令行中键入程序时计算机搜索程序的位置。您可以使用 echo $PATH 查看您的路径。

标准规定 PATH 中的所有路径不应以斜杠结尾。因此， Homebrew 程序要求您修复它。

nano ~/.bashrc 或 nano ~/.bash_profile 并查找“/usr/local/git/bin/”并删除尾部斜杠。
