运行manage.py报错 TypeError: unsupported operand type(s) for : ‘str‘ and ‘str‘

运行manage.py报错 TypeError: unsupported operand type(s) for /: ‘str‘ and ‘str‘

1.Terminal运行

python manage.py runserver 8000

报错TypeError: unsupported operand type(s) for /: 'str' and 'str'

2.解决setting.py中

'DIRS': [base_DIR / 'templates']改为

'DIRS': [str.format(base_DIR, '/templates')]

3.回到manage.py运行成功
