Answer 1

从命令行执行

where git

你可能会得到两个地点

/usr/bin/git
/usr/local/bin/git

那就去做

 /usr/bin/git --version

你应该去

git version 2.5.4 (Apple Git-61)

这是Mac附带的安装版本。

然后检查此路径上的版本。

/usr/local/bin/git --version
git version 2.7.1

这是当前的版本

然后检查你的路径

echo $PATH

并确保'/usr/local/bin/‘在您的路径的早期，否则它将不会执行git命令，如果不编辑您的路径。
