我试图运行brew更新,我得到一个关于我的本地更改将丢失的错误,如果我合并。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。

输出如下:

Error: Failed while executing git pull  origin refs/heads/master:refs/remotes/origin/master

几周前,我在更新旧的自制程序安装时遇到了类似的问题。这样做:

git reset --hard origin/master

在/usr/local中为我修复了它。

似乎其他人也有这个问题。你看了这里提出的变通方案了吗?


别忘了获取原点:

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

发生的情况是,您试图更新brew,但brew本身不是最新的(可能),通过某些操作系统更新有权限更改(也可能),或者brew轻微损坏(不太可能)。由于brew本身是一个git回购,您必须更新或重置brew到主分支版本。brew[默认情况下]位于/usr/ localhome brew文件夹中

转到该文件夹[第一个命令],它也应该更新权限(如果没有,请参阅下面) 获取origin [second命令],这意味着更新brew远程分支的LOCAL版本 基于REMOTE主分支(也使用您的当前权限)的硬复位[第三个命令]。

如果您在非sudo或admin配置文件中,也可以删除第一个命令

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

要理解git重置,可以看看这篇文章。


我加上我的个人经验,因为这似乎比2012年提出的建议更安全:

Run brew doctor. If you get the following warning: Warning: The /usr/local directory is not writable. run: sudo chown -R `whoami` /usr/local to fix the permissions problems (as suggested also by Chris Frisina). Eventually run brew doctor again to ensure yourself that the warning is gone. Now, you should have a Warning: You have uncommitted modifications to Homebrew that may bey solved by cd /usr/local/Library && git stash && git clean -d -f as suggested by Dr.Brew itself. The command stashes the uncommitted modifications so you could go back and recover them if needed. It seemed safer than git reset --hard origin/master to me. If you wish, check the official troubleshooting guide if the steps suggested here and by other SO users does not solve your problem.


类似的答案,但如果你有文件不再被跟踪,你需要额外的步骤,所以从/usr/local运行

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

这种方法可能比其他方法更简单。它包括:

修复了一个git问题,这样您就可以再次委托管理更改了。 不需要手动移动文件或目录。 不需要手动调整文件或目录权限。

步骤(需要解释的人可以做笔记):

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回购url的变化。现在已经煮好了,以前也是,少不更事的人。(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引导到正确的目录。对我来说,目录结构与上面显示的其他目录(Mac OS 10.11.16)不同,但是使用这个命令,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添加到新的别名;我这样做只是为了防止这种方法没有达到我想要的效果,我又需要以前的地址。由于新的远程工作,我将邀请其他人对简单地更改url以起源为别名进行评论。我将很高兴地更新答案,以反映对您有效的方法。

注意3:这个第四个命令得到了理想的结果:它报告了大量的更新,包括特别漂亮的报告“==> migrate HOMEBREW_REPOSITORY to /usr/ localhome brew!”(并强调了这一点)。
