我尝试运行brew update,但如果我合并我的本地更改将会丢失。我尝试提交我的本地更改(不记得做过任何更改,但已经有一段时间了),这让事情变得更糟。

这是输出:

不要忘记获取原点:

cd /usr/local/Homebrew
git fetch origin
git reset --hard origin/master

发生的情况是您正在尝试更新 brew,但 brew 本身不是最新的(可能),通过某些操作系统更新发生了权限更改(也可能),或者 brew 稍微损坏(不太可能)。由于 brew 本身是一个 git repo,因此您必须将 brew 更新或重置为 master 分支版本。brew [默认] 位于/usr/local/Homebrew文件夹中,所以你

  1. 转到该文件夹​​[第一个命令],它也应该更新权限(如果没有见下文)
  2. 获取原点 [第二条命令],这意味着更新 brew 远程分支的本地版本
  3. 基于远程主分支(也使用您当前的权限)的硬重置 [3rd command]。

chown如果您在非 sudo 或管理员配置文件中,您也可以使用第一个命令

sudo chown -R `whoami` /usr/local/Homebrew
cd /usr/local/Homebrew
git reset --hard origin/master

要了解 git reset,请查看这篇文章

几周前我遇到了类似的问题,试图更新旧的自制软件安装。这样做:

git reset --hard origin/master

/usr/local我修好了。

似乎其他人也有这个问题。您是否查看过这里提出的任何解决方法?

我正在添加我的个人经验,因为它似乎比 2012 年提出的更安全:

  1. 运行brew doctor
  2. 如果您收到以下警告:

    Warning: The /usr/local directory is not writable.
    

    跑:

    sudo chown -R `whoami` /usr/local
    

    修复权限问题(也由 Chris Frisina 建议)。最终brew doctor再次运行以确保警告消失。

  3. 现在,你应该有一个

    Warning: You have uncommitted modifications to Homebrew
    

    可以通过以下方式解决

    cd /usr/local/Library && git stash && git clean -d -f
    

    正如 Dr.Brew 本身所建议的那样。该命令存储未提交的修改,以便您可以在需要时返回并恢复它们。这似乎比git reset --hard origin/master我更安全。

  4. 如果您愿意,如果此处和其他 SO 用户建议的步骤不能解决您的问题,请查看官方故障排除指南。

类似的答案,但如果您有不再跟踪的文件,则需要额外的步骤,因此从/usr/local运行

git fetch origin
git clean -f
git reset --hard origin/master

这种方法可能比某些方法更简单。它涉及:

  • 修复 git 问题,以便您可以再次将更改的管理委派给它。
  • 无需手动移动文件或目录。
  • 无需手动调整文件或目录权限。

步骤(为需要解释的人提供注释):

cd $(brew --repository)                              // see Note 1 below
git remote add brew https://github.com/Homebrew/brew // see Note 2 below
git pull brew master                                 // promising fast-forward report!
brew update                                          // see Note 3 below 

概述:
据我所知,这个问题的实际原因是 repo url 发生了变化。现在brew和过去brew.git。(完整的最新网址:https ://github.com/Homebrew/brew )

注意 1:第一个命令将您从文件结构中的任何位置带到正确的目录。对我来说,目录结构与上面显示的其他人(Mac OS 10.11.16)不同,但是使用此命令,这些差异应该无关紧要。

注意 2:第二个命令将正确的远程 url 添加到新别名;我这样做是为了以防这种方法没有完成我想要的并且我再次需要以前的地址。由于新的遥控器工作正常,我会邀请其他人评论简单地更改以来源为别名的 url。我很乐意更新答案以反映对您有用的方法。

注意 3:这第四条命令完全符合预期的结果:它报告了大量更新,包括特别好的报告“==> Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew!” (强调他们的)。
