问题:

学习github上大佬的python教程(42天)时遇到的问题

django中,为了创建models.py

python manage.py inspectdb > polls/models.py

python manage.py shell

执行这句后就出现了

Traceback (most recent call last):

    main()

ValueError: source code string cannot contain null bytes

ValueError: source code string cannot contain null bytes

排查结果:

python manage.py inspectdb > polls/models.py
生成出来的文件models.py的文件格式不是utf8导致

解决方法

使用 notepad++ 等编辑器打开 models.py 改成 utf8格式就行了
