在 Windows 下使用 Git
如果只在git bash 上配置 Git 并使用 SSH 授权，Git 会在HOME 环境指向的目录中查找 SSH 密钥。该变量总是由git bash 设置。
不过，Windows 命令提示符通常不会设置该变量。在 Windows 命令提示符下运行 Git 时，它会在安装目录下查找 SSH 密钥，因此授权会失败。
你可以通过Qt Creator 设置HOME 环境变量。转到 "偏好设置" >Version Control >Git ，然后选择Set "HOME" environment variable 。运行 Git 可执行文件时，HOME 会被设置为%HOMEDRIVE%%HOMEPATH% ，授权也会像git bash 一样生效。
