python - TypeError：Django 社交登录中的格式字符串参数不足

问题描述

我正在使用 social-auth-app-django 进行 Google 身份验证。每当我尝试使用 google 登录或管理页面时，都会遇到此错误。 在此处输入图像描述

我已在 settings.py 、视图和模板中正确添加了所有内容。

Traceback (most recent call last):
  File "C:\Data Science\python_files\temop\lib\site-packages\social_core\backends\utils.py", line 50, in get_backend
    return BACKENDSCACHE[name]

During handling of the above exception, another exception occurred:

    TypeError: not enough arguments for format string

该错误似乎与 social-auth-app-django 模块有关。

SOCIAL_AUTH_URL_NAMESPACE = 'social'#
SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = 'SOCIAL_GOOGLE_KEY'  #Paste CLient Key
SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = 'SECRET KEY'
AUTHENTICATION_BACKENDS = (
    'social_core.backends.google.GoogleOAuth2',
    'django.contrib.auth.backends.ModelBackend',
)

网址.py

path('', include('social_django.urls', namespace='social')),

登录.html

    <a href="{% url 'social:begin' 'google-oauth2' %}" class="google btn"><i class="fa fa-google fa-fw">

解决方案

我遇到了这个问题，并通过在我的虚拟环境中切换 python 版本来解决它。

这是由于一个 django 依赖项和 python 版本之间的冲突。错误发生在python 3.8django 2 上的虚拟环境中。在 中创建新的虚拟环境python 3.6并重新安装所有要求修复了它。
