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。

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

复制代码

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

1. from django.utils.encoding import smart_text
2. from six import python_2_unicode_compatible

复制代码

问题3、ImportError: cannot import name 'pretty_name' from 'django.forms.forms'

2.     from django.contrib.staticfiles.templatetags.staticfiles import static
3. ModuleNotFoundError: No module named 'django.contrib.staticfiles.templatetags'

复制代码

2.     from django.utils.functional import memoize
3. ImportError: cannot import name 'memoize' from 'django.utils.functional'

复制代码

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：

1. from functools import lru_cache

复制代码

3. 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'

复制代码

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

修改为：

1. from django.utils.functional import keep_lazy

复制代码

解决2：同一个文件下，第20行，导入错误问题
