git clone工程中的分支fatal: unable to auto-detect email address

仓库中有很多分支时，git clone 对应的URL只能clone下master主分支，这是需要新建对应的分支

git checkout -b POC #新建POC分支

再拉取对应的代码

git pull origin POC

遇见报错

fatal: unable to auto-detect email address 

查了一下，设置邮箱密码也还是一样

sudo git config --global user.email "[email protected]"
[sudo] password for ytj: 
ytj@ubuntu:~/PictorFaceSDK$ sudo git config --global user.name "yangjiang"

原来是没切换用户身份，运行su命令，输入密码，再拉取POC分支集问题解决

ytj@ubuntu:~/PictorFaceSDK$ git branch -d POC
