我有一个刚刚启动的ec2实例。当我尝试克隆我的回购时，我已经多次完成git，只是退出而没有克隆，从不提示输入我的用户名和密码。任何人都可以说出可能导致问题的原因吗？
这是一个git trace：
[root@ip-IP html]# GIT_TRACE=1 git clone https://github.com/USER/seooverflow.git
trace: built-in: git 'clone' 'https://github.com/USER/seooverflow.git'
Cloning into 'seooverflow'...
trace: run_command: 'git-remote-https' 'origin' 'https://github.com/USER/seooverflow.git'
[root@ip-IP html]#
这是一部分，因为我限于30000个字符：
