django - 导入错误 : cannot import name 'force_unicode' caused another exception

Question

我在我的 django 应用程序中玩日历，所以我做了一个:

pip3 安装 django-scheduler

( https://github.com/llazzaro/django-scheduler )

我做我通常的 python3 manage.py runserver 的那一刻它失败了，这个长异常:

Exception in thread django-main-thread:
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/filer/utils/compatibility.py", line 71, in <module>
    from django.utils.encoding import force_unicode  # noqa
ImportError: cannot import name 'force_unicode'

During handling of the above exception, another exception occurred:

    from django.utils.encoding import python_2_unicode_compatible  # noqa

我想'哦不，没问题我只是 pip3 卸载 django_scheduler'

好吧，我这样做了(在我的 INSTALLED_APPS 中删除了“计划”的添加)并尝试重新运行，但再次出现相同的错误。那么我是否只是无可救药地破坏了我的整个项目？

Python 版本为:3.6.8
Django 版本:3.0.6

我很高兴地编码，直到我有一个尝试使用 django 库来实现我需要实现的日历而不是仅仅编写我自己的脑电波:/

有一个不适用于此功能的向后兼容性 promise

只需更换 force_unicode与 force_text如果您使用最近的 Django 版本。

它在 py2 和 py3 上都适用于 Django1.11。
