manage.py runserver 语法无效

Question

更新

我无意中编辑了 manage.py 文件。

manage.py文件中的代码需要是-

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys


def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'django_project1.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)


if __name__ == '__main__':
    main()

然后在 CMD (Windows Key + R) 中输入 -

C:\Users\HP\django_project1\django_project1>cd C:\Users\HP\django_project1

原始问题 我正在尝试运行命令python manage.py runserver、$python manage.py runserver 和$ python manage.py runserver，但不断出现错误。

我尝试过python manage.py runserver、manage.py runserver 和python3 manage.py runserver。

由于某种原因，您似乎编辑了 manage.py 文件，使其包含文本“python3 manage.py runserver”。我不知道你为什么这样做，但你应该删除它。
