因此，出于某些原因，我使用Ruby命令从计算机上卸载了Homebrew，该命令说“这将卸载Brew附带的所有软件包”。我这样做了，现在当我尝试再次安装Homebrew时，出现Git错误，提示“请确保您具有正确的访问权限”。
我认为此错误是因为卸载Brew卸载了Git，但是当我键入“ git --version”时，我得到了“ git version 2.15.0”，所以这不是问题。
然后，我生成了一个新的SSH密钥，并将公共密钥添加到了我的git帐户。做
ssh -T git@github.com
给我
Hi {{username}}! You've successfully authenticated, but GitHub does not provide shell access
即使我尝试git克隆自己的仓库，我也会遇到相同的错误：
ERROR: Repository not found.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
这是Brew安装的日志

我还手动删除了/ usr / local / Homebrew。这是卸载Brew的命令：
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
编辑：我刚刚从计算机上卸载了git，但仍然遇到相同的错误。不知道发生了什么事！
