我在日志中得到了这个，在将 python 从 2.7 升级到 3.5 后，没有完整的堆栈跟踪，我不知道如何解决这个问题。

/root/.virtualenvs/python3/lib/python3.5/site-packages/django/template/loader.py:97: RemovedInDjango110Warning: render() must be called with a dict, not a RequestContext.
  return template.render(context, request)

2018-02-24 21:53:07,452 - WARNING - django - /root/.virtualenvs/python3/lib/python3.5/site-packages/django/template/loader.py:97: RemovedInDjango110Warning: render() must be called with a dict, not a RequestContext.
  return template.render(context, request)

我做到grep -rl --include \*.py 'Context('了，没有显示任何内容，不仅限于 python 文件，它会给我一堆 JavaScript 文件（React）。

Django==1.9.3

升级到 Django==1.10 会给我更多我不知道如何修复的错误。

在 Django 1.10 发行说明中它有

“由 get_template() 和 select_template() 返回的 Django 模板对象在其 render() 方法中不再接受 Context。”

这可能会导致警告。1.10 的发行说明在这里：https ://docs.djangoproject.com/en/2.0/releases/1.10/

另外，如果您还不知道 1.9 不再是受支持的 Django 版本
