自制致命：需要单一版本（MacOs Sierra） [英] Homebrew fatal: needed a single revision (MacOs Sierra)

问题描述

不知道这个问题是否与升级到MacOs Sierra有关，但从那一刻起，当我运行'brew update'时发生这个错误。

我试过运行

  cd $（brew --prefix）&& git fetch&& git reset --hard origin / master 
  

但它给了我这个错误：

  fatal：不是git存储库（或任何父目录）：.git 
  

解决方案

升级到Sierra后，我遇到了同样的问题。除了显示Homebrew的安装路径，还有 brew --prefix ，它还显示了它的位置 .git 目录位于

man brew 说声称对于标准安装，前缀和存储库是相同的目录。手册页已过期，或者我的安装不是标准，但是我的前缀是 / usr / local 和我的仓库是 / usr / local / Homebrew 。

使用相同的命令，但使用 cd $（brew --repository）为我工作：

  cd $（brew --repository）&& git fetch&& git reset --hard origin / master 
  

Not sure if this problem is related to upgrading to MacOs Sierra, but since that moment this error occurs when I run 'brew update'

I tried running

cd $(brew --prefix) && git fetch && git reset --hard origin/master

But it gives me this error:

fatal: Not a git repository (or any of the parent directories): .git

解决方案

I had the same problem after upgrading to Sierra.

In addition to brew --prefix, which displays Homebrew’s install path, there’s also brew --repository, which displays where it’s .git directory is located.

man brew says that claims that "for standard installs, the prefix and repository are the same directory". Either the man page is out of date or my install isn’t "standard", but my prefix is /usr/local and my repository is /usr/local/Homebrew.

Using the same command but with cd $(brew --repository) worked for me:

cd $(brew --repository) && git fetch && git reset --hard origin/master
