Github错误：fatal: Authentication failed for 'https://github.com/ ...

GitHub push代码发生错误：fatal: Authentication failed for ‘https://github.com/ …

使用的https提交，在用SourceTree提交代码时候发生错误，返回的错误提示说：

fatal: Authentication failed for 'https://github.com/ ...   

解决方案，重新执行git config命令配置用户名和邮箱即可：

git config -–global user.name "xxx"   
git config –-global user.email "xxx@xxx.com"
