自制软件更新git在mac上

Question

我正在尝试切换到自制软件的git版本，但我收到以下消息：

unknown68a86d401752:~ davidadams$ brew link git
Linking /usr/local/Cellar/git/1.8.4... Warning: Could not link git. Unlinking...

Error: Could not symlink file: /usr/local/Cellar/git/1.8.4/share/zsh/site-functions/git-completion.bash
Target /usr/local/share/zsh/site-functions/git-completion.bash already exists. You may need to delete it.
To force the link and overwrite all other conflicting files, do:
  brew link --overwrite formula_name

To list all files that would be deleted:
  brew link --overwrite --dry-run formula_name

我对Homebrew或垃圾箱知之甚少，不知道这是否安全。

我的目标是开始使用当前版本的git。终端告诉我以下内容：

unknown68a86d401752:~ davidadams$ which git
/usr/bin/git
unknown68a86d401752:~ davidadams$ git --version
git version 1.7.7.5 (Apple Git-26)

Answer 1

嗯，git-completion.bash可能无论如何都没有改变，但是因为你正在更新git以使用更新的版本，所以获取该脚本的新版本应该没问题。
