最近我的Unison应用程序已停止在我的Mac终端上工作，说无法找到该命令。不确定这是不是因为我最近重新安装了brew（它是如何安装的），这可能会破坏它。
以下是错误输出：
mac:~ Imran$ unison sites
-bash: unison: command not found
我可以看到，如果在以下目录中找到locate unison unison：
> /Users/Imran/unison.log /Users/Imran/unison.tar.gz

有人可以帮助我重新开始工作吗？我怀疑它与应用程序被破坏的链接有关。

如果您重新安装了一个酿酒桶，那么如果您在路径中找不到它，则可能需要再次手动链接它。
brew link unison

根据documentation，错误消息bash: unison: command not found表示：
确保您要连接的主机上已安装Unison。

（或运行更新的 macOS 版本，其中 zsh 是默认值），您必须修改或创建 zsh。
通过将以下代码段之一添加到 ~/.zshenv 来添加 shell 环境的路径。
对于 ARM64（M1 Mac）：
~/.zshenv或在 x86（英特尔 Mac）上
eval $(/opt/homebrew/bin/brew shellenv)
或者您只是获取您的eval $(/usr/local/bin/brew shellenv)

您用户的 PATH 变量不包含指向 unison 二进制文件的链接。
将/usr/local/Cellar/unison/2.40.102/bin/unison添加到.bashrc，
$ vi ~/.bashrc
添加以下内容，
export PATH=$PATH:/usr/local/Cellar/unison/2.40.102/bin/unison
保存并退出，然后重新读取您的用户bashrc文件，
exec bash
现在再次尝试哪个联合，或者实际上只是尝试使用
运行它$ unison
