php – 当使用具有私有VCS的composer时,它无限地要求授权

{
    "type": "vcs","url": "https://github.com/username/repo.git"
}

当我调用php composer.phar更新时,我得到以下内容：

Your GitHub credentials are required to fetch private repository metadata (https://github.com/username/repo.git)
The credentials will be swapped for an OAuth token stored in /root/.composer/config.json,your password will not be stored
To revoke access to this token you can visit https://github.com/settings/applications

Username: myusername
Password:
    Authentication required (api.github.com):
      Username: myusername
      Password:
    Authentication required (api.github.com):
      Username: myusername
      Password:
    Authentication required (api.github.com):
      Username:

无论我多少次投入我的github凭据,它一直在问.如果我输错了它会做同样的事情,没有错误或最大尝试.

任何想法会导致什么？我通过运行使用最新版本可检索：

php composer.phar self-update

周围的工作

作为一个现在的解决方法我已经去过：https://github.com/settings/applications并手动生成令牌然后运行：

php composer.phar config -g github-oauth.github.com <token>

但我仍然想知道为什么它不能自动完成
