Python 如何修复将django 1.10升级到1.11时出现的错误？

将django从1.10升级到1.11后，我无法使用

manage.py

命令。有这么多的错误，我甚至不知道从哪里开始，从哪里寻找错误的原因。如果有任何帮助，我将不胜感激

我将所有错误粘贴到下面

您的

pip install-U

命令已将easy缩略图升级到

2.7.0

，但该版本适用于Django 1.11.X

在2.5.0中添加了对Django 1.11的支持，因此2.5.0或2.6.0都可以工作（取决于其他需求）。您可以通过以下方式安装2.6：

pip install --upgrade "easy-thumbnails<2.7.0"

---

pip-install--upgrade“easy thumbnails”看起来像是在第三方软件包中，您应该根据更改文件将“easy thumbnails”软件包升级到2.5.0或更高版本。始终从下到上查看错误跟踪。此特定消息告诉您
Settings（）
不能这样初始化，因为超类的初始化器中需要一个附加参数。因此，您的“简易缩略图”版本可能与django 1.11不兼容。我建议您跳过django 1.11，直接转到2.2（当前的LTS版本）。您将遇到从1.11到2.2的新问题（您需要在4月之前完成）。@dirkgroten我自己对django升级的经验是，通常更容易通过所有“中间层”“版本-这当然很无聊，但至少你不会一次做太多更改，而且你可以按照每个版本的更改列表进行操作。IIRC这也是Django的官方建议（但不要让我找到它的参考）@dirkgroten尽管如此，我还是找到了它：“如果你通过多个功能版本（例如a.B到a.B+2）进行升级，通常通过每个功能版本（a.B到a.B+1到a.B+2）进行增量升级比较容易。”而不是一次对每个功能版本进行所有更改。对于每个功能版本，请使用最新的修补程序版本（A.B.C）。“（）
pip install --upgrade "easy-thumbnails<2.7.0"
