Couldn't save uncommitted changes.
Tried to save uncommitted changes in stash before Update, but failed with an error.
stash file://E:/work/asset: unable to auto-detect email address (got '[email protected](none)')
Cannot save the current index state
原因：
第一，凭据错误：如果输错了git用户名密码，无法再次修改，可以去 控制面板-用户账户-凭据管理器-windows凭据找到git相关的密码去修改就好了：
第二：如果此时还不能pull你的项目，报上面的Couldn't save uncommitted changes错误，你只需要提交一个文件，然后再次pull就能正常pull了！
