python - 线程 django-main-thread 中的异常

Question

我正在使用 oauth2client 库实现 google 登录，并在 /google-login/myvenv/lib/python3.5/site-packages/oauth2client/contrib/django_util/__init__.py 中做了一些更改 刚刚将 from django.core import urlresolvers 替换为 from django.urls import reverse 并将第 411 行 urlresolvers.reverse(...) 替换为 反向(...) 在运行我的服务器时 python manage.py 运行服务器 发生类型错误 这个错误的回溯是:

Watching for file changes with StatReloader
Exception in thread django-main-thread:

TypeError: __init__() missing 2 required positional arguments: 'doc' and 'pos'

得到这个回溯 我不知道这是什么意思。

Answer 1

我的 client_secrets.json 文件中存在语法错误。 修复后，它起作用了。 感谢 AKX 指出。
