Python：Django - 与manage.py中的代码调试器错误

Question

问题：manage.py中的VS Code调试器，在django中启动新项目时会生成这些代码

修改

实际错误：

user@user:~/PROJ/py/lib$ cd /home/user/PROJ/py/lib ; env "PYTHONIOENCODING=UTF-8" "PYTHONUNBUFFERED=1" python /home/user/.vscode/extensions/ms-python.python-2018.3.1/pythonFiles/PythonTools/visualstudio_py_launcher.py /home/user/PROJ/py/lib 42135 34806ad9-833a-4524-8cd6-18ca4aa74f14 RedirectOutput,RedirectOutput,DjangoDebugging /home/user/PROJ/py/lib/manage.py runserver --noreload --nothreading File "/home/user/PROJ/py/lib/manage.py", line 14 ) from exc ^ SyntaxError: invalid syntax

manage.py：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "lib.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)

这是我在launch.json中的配置：

{
    "name": "Python: Django",
    "type": "python",
    "request": "launch",
    "program": "${workspaceFolder}/manage.py",
    "args": [
        "runserver",
        "--noreload",
        "--nothreading"
    ],
    "debugOptions": [
        "RedirectOutput",
        "Django",
    ]
}
