我是这样做的:

打开安装在Mac上的GitHub应用程序 单击高级选项卡→安装命令行工具 一旦您收到一条消息，提示所有命令都已安装，请关闭终端并重新打开。 现在检查git——version，它会给你最新的版本。

在macOS上，Monterey homebrew将二进制文件放在/opt/homebrew/bin

将此添加到.bash_profile将优先于自制git而不是apple-git

export PATH=/opt/homebrew/bin:$PATH

在谷歌上搜索“在mac上升级git遇到麻烦”后，我阅读了几篇文章，并尝试了以下步骤，然后通过完成步骤4解决了问题:

I updated my terminal path by using the above mention export command. Every time I quit the terminal and restarted it, when I typed git --version the terminal, it still return the older version 1.8. I followed the README.txt instructions for upgrading to the current version 2.0.1 that comes with the .dmg installer and when I restarted the terminal, still no go. I looked for /etc/path/ folder as instructed above and the directory called "path" does not exist on my Mac. I am running OS X Mavericks version 10.9.4. Then I recalled I have Homebrew installed on my Mac and ran the following: brew --version brew update brew search git brew install git

这终于解决了我的问题。如果有人有一些见解，为什么这工作，进一步的见解将大大赞赏。我的系统上可能还有一些去年使用Ruby时遗留下来的路径设置。

我使用以下方法在mac上升级git。

hansi$ brew install git 

hansi$ git --version 
git version 2.19.0


hansi$ brew install git
Warning: git 2.25.1 is already installed, it's just not linked
You can use `brew link git` to link this version.

hansi$ brew link git 
Linking /usr/local/Cellar/git/2.25.1... 
Error: Could not symlink bin/git
Target /usr/local/bin/git
already exists. You may want to remove it:
  rm '/usr/local/bin/git'

To force the link and overwrite all conflicting files:
  brew link --overwrite git

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

hansi$ brew link --overwrite git 
Linking /usr/local/Cellar/git/2.25.1... 205 symlinks created


hansi$ git --version
git version 2.25.1

如果使用自制，您可以更新sim链接使用

brew link --overwrite git

如果你能补充以下内容可能会更好:

export PATH=/usr/local/git/bin:/usr/local/sbin:$PATH

到主文件夹中名为.bashrc的文件。这样，您可能安装在/usr/local/git/bin中的任何其他软件也将首先被找到。

一个简单的方法就是输入:

echo "export PATH=/usr/local/git/bin:/usr/local/sbin:$PATH" >> ~/.bashrc

到终点站，它会为您办理的。
