Homebrew在安装过程中无法链接Git

Question

我似乎无法解决这个问题。在安装过程中，Homebrew 无法链接 git。终端输出如下：

我尝试运行:

brew link git

除了卸载和重新安装外。 我的 /etc/paths 文件目前如下：

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

有什么线索吗？ 哦，我也安装了GitHub的Mac应用程序（如果有影响的话？）

Answer 1

看起来与 GitHub 应用程序存在冲突，建议卸载该应用，您并不需要它。

我与一些人谈过这个问题，他们说这个应用有点不稳定，使用终端会更好（我也同意这一点）。

编辑：brew update brew upgrade 然后运行 brew doctor 可以提供更多线索。

谢谢，这个很有帮助。运行了 brew doctor 命令，它建议在几个文件夹上使用 chown 命令。执行了该命令，然后重新运行 brew install git，现在一切都正常工作了！ :) - Jonathan

Answer 2

公式已经构建完成，但未创建符号链接到 /usr/local。

尝试通过以下方式覆盖链接：

brew link --overwrite git

添加 --dry-run 以查看它影响哪些文件。

如果仍然失败，请尝试修复您的 Homebrew 权限：

sudo chown -R $USER /usr/local/lib /usr/local/include /usr/local/bin /usr/local/Cellar
