Question

我在django应用中正在使用日历，所以我做了：

pip3安装django-scheduler

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

我执行我通常的python3 manage.py runserver的那一刻，由于出现了这么长的异常而失败了：

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:

我以为“哦，不，没问题，我将pip3卸载django_scheduler”

好吧，我做到了（删除了在我的INSTALLED_APPS中添加了“时间表”）并尝试重新运行，并再次遇到相同的错误。那我只是无望地打破了我的整个项目吗？

Python版本是：3.6.8 Django版本：3.0.6

我一直很开心地编码，直到我开始尝试将django库用于我需要实现的日历，而不是仅仅编写自己的：/

存在向后兼容的保证，thas不适用于此功能

如果使用最新的Django版本，只需将force_unicode替换为force_text。

它在py2和py3上都适用于Django1.11。

ImportError：无法导入名称'force_unicode'导致了另一个异常
