問題&解決

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

解決：在site-packages目錄中找到six.py文件，將其複製到django/utils目錄下。

問題2、ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding'

File "D:\Python310\.virtualenv\Wuwuchong\Lib\site-packages\xadmin\models.py", line 11, in <module>
      from django.utils.encoding import python_2_unicode_compatible, smart_text
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding'

解決：將from django.utils.encoding import python_2_unicode_compatible, smart_text
註釋掉並改為：

from six import python_2_unicode_compatible

解決：將 from django.forms.forms import pretty_name
註釋掉並改為：

from django.utils import formats, six

問題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.contrib.staticfiles.templatetags.staticfiles import static

from django.templatetags.static import static

問題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>

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'

解決：這個問題我沒有找到解決辦法，不過從前面看只要24行沒有報錯就不會走到這裡來。
百度一下，發現在Django 3.2中，django.utils.lru_cache.lru_cache模塊已經被移除，因為Django 3.2中不再使用LRU緩存，而是改用內置的標準庫中的functools.lru_cache。
將24行註釋掉並改為：

from functools import lru_cache

問題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'

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

修改為：

from django.utils.functional import keep_lazy

解決2：同一個文件下，第20行，導入錯誤問題

修改為：

remove_spaces = keep_lazy(remove_spaces, text_type)
