Faker()引发Django配置不当错误
试图使用Faker运行一些虚假数据,但已经尝试了2天来解决,我无法。我需要一点帮助,下面是代码和错误。我尝试了多种方法尝试access Django的设置模块,但它不起作用,我相信问题出在第10行os.eniron…等等 我正在使用Windows10、Sqlite、Python3.8.2、Django3和venv环境python-m venv name 我已经在django管理员我不知道现在会是什么问题。。。 任何帮助都将不胜感激。谢谢大家! 首先测试应用程序pyFaker()引发Django配置不当错误,django,python-3.x,django-models,django-views,Django,Python 3.x,Django Models,Django Views,试图使用Faker运行一些虚假数据,但已经尝试了2天来解决,我无法。我需要一点帮助,下面是代码和错误。我尝试了多种方法尝试access Django的设置模块,但它不起作用,我相信问题出在第10行os.eniron…等等 我正在使用Windows10、Sqlite、Python3.8.2、Django3和venv环境python-m venv name 我已经在django管理员我不知道现在会是什么问题。。。 任何帮助都将不胜感激。谢谢大家! 首先测试应用程序py import django i
