Wagtail:编译项目时文件路径错误

Question

我正试图将Wagtail从1.13升级到2.0，在尝试迁移时遇到了这个错误：

RuntimeError: Model class wagtail.wagtailcore.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

日志是：

[...]
File "C:  Program Files  Python36  lib  site-packages  wagtail  wagtailcore  blocks  field_block.py", line 16, in <module>
from wagtail.wagtailcore.rich_text import RichText
File "C:  Program Files  Python36  lib  site-packages  wagtail  wagtailcore  rich_text.py", line 10, in <module>
from wagtail.wagtailcore.models import Page
File "C:  Program Files  Python36  lib  site-packages  wagtail  wagtailcore  models.py", line 54, in <module>
class Site (models.Model):
File "C:  Program Files  Python36  lib  site-packages  django  db  models  base.py", line 118, in __new__
"INSTALLED_APPS." % (module, name)
RuntimeError: Model class wagtail.wagtailcore.models.Site doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

我之前已经安装了更新所需的一切，并且我已经传递了重命名更改字段的脚本。

在日志中，您可以看到应该指向核心的路径实际上指向旧版本(wagtailcore(，而不是"；核心"：

C:  Program Files  Python36  lib  site-packages  wagtail  wagtailcore  models.py

我想所有的问题都来自这里，我该如何在django中查找正确的文件夹？

更新：

我试图用pip卸载wagtail卸载，但一些文件夹没有被删除：结果卸载后

命令抛出以下错误：

Answer 1

在Wagtail 2.0的代码库中根本不存在wagtailcore应用程序文件夹，所以看起来您仍然安装了旧版本的Wagtail。尝试运行pip uninstall wagtail，并在运行pip install wagtail==2.0.2之前确认已正确删除C:Program FilesPython36libsite-packageswagtail文件夹。
