错误指向源代码中的以下行
if not user_exists:
if self.create_system_users:
await maybe_future(self.add_system_user(user))
else:
raise KeyError("User %s does not exist." % user.name)
await maybe_future(super().add_user(user))
这意味着只有当self.create_system_users = False（默认值）时才会抛出错误
但我已经在jupyterhub_config.py
中将其设置为Truec.LocalGitHubAuthenticator.create_system_users = True

答案 0 :(得分：1)
在jupyterhub_config.py中自己解决问题，它应该是
c.LocalAuthenticator.create_system_users = True
