问题&解决

问题1、ImportError: cannot import name 'six' from 'django.utils'

解决：在site-packages目录中找到six.py文件，将其复制到django/utils目录下。

      from django.utils.encoding import python_2_unicode_compatible, smart_text
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding'

解决：将from django.utils.encoding import python_2_unicode_compatible, smart_text
注释掉并改为：

解决：将 from django.forms.forms import pretty_name
注释掉并改为：

from django.utils import formats, six

问题4、ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'

File "D:\Python310\.virtualenv\Wuwuchong\Lib\site-packages\xadmin\utils.py", line 25, in <module>

from django.templatetags.static import static

问题5、ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding'

File "D:\Python310\.virtualenv\Wuwuchong\Lib\site-packages\reversion\revisions.py", line 16, in <module>
    from django.utils.encoding import force_text, python_2_unicode_compatible

解决：注释掉并改为：

from django.utils.encoding import force_text
from six import python_2_unicode_compatible

问题6、ModuleNotFoundError: No module named 'django.core.urlresolvers'

File "D:\Python310\.virtualenv\Wuwuchong\lib\site-packages\crispy_forms\compatibility.py", line 26, in <module>
    from django.utils.functional import memoize
ImportError: cannot import name 'memoize' from 'django.utils.functional'

解决：这个问题我没有找到解决办法，不过从前面看只要24行没有报错就不会走到这里来。
百度一下，发现在Django 3.2中，django.utils.lru_cache.lru_cache模块已经被移除，因为Django 3.2中不再使用LRU缓存，而是改用内置的标准库中的functools.lru_cache。
将24行注释掉并改为：

from functools import lru_cache

问题9、ModuleNotFoundError: No module named 'django.core.urlresolvers'

File "D:\Python310\.virtualenv\Wuwuchong\lib\site-packages\crispy_forms\helper.py", line 4, in <module>

django.template.library.InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'crispy_forms.templatetags.crispy_forms_utils': cannot import name 'allow_lazy' from 'django.utils.functional'

解决1：需要修改site-packages\crispy_forms\templatetags\crispy_forms_utils.py文件第6行

修改为：

from django.utils.functional import keep_lazy

解决2：同一个文件下，第20行，导入错误问题

修改为：

remove_spaces = keep_lazy(remove_spaces, text_type)
