将 django_social 添加到 INSTALLED_APPS 时出现“TypeError：'map' 类型的对象没有 len()”错误

Question

我正在尝试实现 django 社交身份验证，为此我做了pip install social-auth-app-django，然后我继续将social_django 添加到我的INSTALLED_APPS。之后，当我运行应用程序时，我收到以下错误（我正在提交整个回溯）：

如果我从INSTALLED_APPS 中注释掉“social_django”，一切都会再次正常运行。 我的 python 版本是 3.5.2 和 Django 2.2.12。有任何想法吗 ？我迷路了……

我遇到了这个错误，我通过卸载 python-openid 和 python3-openid 来修复它：

pip uninstall python-openid 

pip uninstall python3-openid

然后重新安装python3-openid 使用：

 pip install python3-openid
