You might be using your GitHub password to log in, but that's no longer possible. But you can still use check50 and submit50! See https://cs50.ly/github for instructions.
Make sure your username and/or personal access token are valid and submit50 is enabled for your account. To enable submit50, please go to
https://submit.cs50.io in your web browser and try again. For instructions on how to set up a personal access token, please visit https://cs50.ly/github
Submission cancelled.

解决步骤 #

• 重置本地submit50认证信息
  先清理终端存储的旧登录凭证，执行命令：

  submit50 logout
  

  重新运行submit50，按提示输入GitHub用户名和个人访问令牌（PAT），注意不能使用GitHub密码。

• 检查个人访问令牌权限
  生成PAT时必须勾选repo和user权限，否则submit50无法访问你的GitHub仓库及账户信息。若旧令牌权限不足，在GitHub账号设置中删除旧令牌，重新生成符合要求的新令牌。

• 确认submit50账户关联状态
  在浏览器登录submit.cs50.io，检查GitHub账号是否成功绑定且账户处于激活状态。若绑定异常，先解除关联后重新绑定账号。

• 更新submit50至最新版本
  旧版本可能存在兼容性问题，执行命令更新：

  pip install --upgrade submit50
