我正在使用python social auth注册登录
我用于注册的网址
<a href= '/login/google-oauth2/'>Signup with Google</a><br/>
<a href= '/login/linkedin/'>Signup with Linkedin</a>
用户首次注册。用户也被创建了。下次当我点击相同的网址时，我收到以下错误
duplicate key value violates unique constraint "people_userprofile_user_id_key"
DETAIL: Key (user_id)=(211) already exists.

我不知道我在做什么错。用户注册后，再次尝试注册该用户而不是登录
