问题&解决

注意：问题1 & 2 & 3 详情和解决办法都是一样的，只是发生问题文件位置不同

问题1. ModuleNotFoundError: No module named 'django.core.urlresolvers'

File "D:\Python310\\.virtualenv\test\lib\site-packages\reversion\admin.py", line 13, in <module>
    from django.core.urlresolvers import reverse
ModuleNotFoundError: No module named 'django.core.urlresolvers'

解决办法： 把报错的行修改为 from django.urls import NoReverseMatch, reverse

问题2. ModuleNotFoundError: No module named 'django.core.urlresolvers'

File "D:\Python310\.virtualenv\test\lib\site-packages\crispy_forms\helper.py", line 4, in <module>
    from django.core.urlresolvers import reverse, NoReverseMatch
ModuleNotFoundError: No module named 'django.core.urlresolvers'

解决办法： 同问题1

问题3. ModuleNotFoundError: No module named 'django.core.urlresolvers'

File "D:\Python310\.virtualenv\test\lib\site-packages\import_export\admin.py", line 16, in <module>
    from django.core.urlresolvers import reverse
ModuleNotFoundError: No module named 'django.core.urlresolvers'

解决办法： 同问题1

问题4. SyntaxWarning: "is" with a literal. Did you mean "=="?

File "F:\Pycharm\Casual\Firsttest\extra_apps\xadmin\filters.py",line 205: SyntaxWarning: "is" with a literal. 
Did you mean "=="?
以及第551行

解决办法： 都是把 is 修改为 ==

问题5. cannot import name 'allow_lazy' from 'django.utils.functional'

File "D:\Python310\.virtualenv\test\lib\site-packages\django\utils\functional.py",
raise InvalidTemplateLibrary(
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'

解决办法： allow_lazy在django1.10 已弃用，请使用 keep_lazy 方法

出处：https://docs.djangoproject.com/en/1.10/ref/utils/#django.contrib.admin.allow_lazy

问题6. NameError: name 'allow_lazy' is not defined

File "D:\Python310\.virtualenv\test\lib\site-packages\crispy_forms\templatetags\crispy_forms_utils.py",
line 20, in <module>
    remove_spaces = allow_lazy(remove_spaces, text_type)
NameError: name 'allow_lazy' is not defined
line 6, 导入错误，from django.utils.functional import allow_lazy

解决办法： 都是把 allow_lazy 修改为 keep_lazy
