当我将 pytz == 2018.7 更新为 pytz == 2019.1 时，我的Django服务器崩溃了。所有时区计算均由Pytz库负责。我问自己是否有所改变，在哪里可以找到变更日志？ 我没有更改Django项目中与时间相关的任何内容，当我回到 pytz == 2018.7 时，一切正常。 我正在将Django 2.2与virtualenv一起使用，这是我的列表
Python==3.7.2
Django 2.2
Virtualenv==16.5.0
Django==2.2
django-widget-tweaks==1.4.3
djangorestframework==3.9.2
Pillow==6.0.0
Pygments==2.3.1
pytz==2018.7
sqlparse==0.3.0
