我试图让一个旧的 Django 项目再次运行。
更新 #1：我删除了参数 extra_thumbnails 和 size 以便服务器正在运行。但是现在我没有正确的图片缩略图......
image = ImageWithThumbnailsField(
upload_to='images',
thumbnail={'size': (120, 120)},
extra_thumbnails={
'icon': {'size': (32, 32), 'options': ['crop', 'upscale']},
'large': {'size': (640, 640)},
}
现在看起来只有：
image = ImageField(
upload_to='images')
--
在似乎解决了旧 sorl.thumbnail 版本和不推荐使用的表达式的问题之后，我现在在运行时收到此错误
python manage.py runserver
我还尝试将我的旧文件复制并粘贴到一个新的 Django 项目中并得到完全相同的错误。也许这里有人知道问题出在哪里？

我需要为本地的可视化文档重新构建项目......所以任何关于如何快速重新运行过时的 django-projects 的提示都非常受欢迎！
非常感谢！
