我有以下代码和以下设置。但我的设置总是出错...... MySQL 版本是 5，Django 是最后一个版本。蟒蛇 3.7

#!/usr/bin/env python
import os
import sys
sys.path.append("/home/test")


if __name__ == "__main__":
     os.environ.setdefault("DJANGO_SETTINGS_MODULE", "standAlone.myScript")
     from django.core.management import execute_from_command_line
     execute_from_command_line(sys.argv)

这是我的 myScript：

# settings.py
from django.conf import settings


#settings.configure(
    DATABASE_ENGINE    = " ",
    DATABASE_NAME      = " ",
    DATABASE_USER      = " ",
    DATABASE_PASSWORD  = " ",
    DATABASE_HOST      = " ",
    DATABASE_PORT      = " ",
   # INSTALLED_APPS     = ("myApp")
)

from django.db import models
from myApp.models import *

这是我的settings.py：

DATABASE_ENGINE    = 'django.db.backends.mysql'
DATABASE_NAME      = 'DATABASE_NAME'
DATABASE_USER      = '****'
DATABASE_PASSWORD  = '****'
DATABASE_HOST      = '127.0.0.1'
DATABASE_PORT      = '3306'

我有以下错误：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/test/django/core/management/__init__.py", line 443, in execute_from_command_line
    utility.execute()

    self._wrapped = Settings(settings_module)
  File "/home/test/django/conf/__init__.py", line 93, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/home/test/django/utils/importlib.py", line 35, in import_module
    __import__(name)

    DATABASE_ENGINE    = "django.db.backends.mysql",

在 myScript.py 的第 5 行中，您有一个#注释行。然后，我认为第 6DATABASE_ENGINE = " ",行将是一个语法错误（尽管回溯似乎不包括这一点）。

还有其他问题。导入内容的方式将导致 settings.py 数据库设置被 myScript.py 中第 5 行以后的空值覆盖。除非这是您想要的，否则执行此操作的正确方法（在 myScript.py 中）是：

# settings.py
from django.conf import settings

from django.db import models
from myApp.models import *

也就是说，在 settings.py 中指定设置，不要在 myScript.py 中覆盖它们。

如果您出于某种原因确实需要覆盖设置，那么只需删除第#5 行，事情可能会奏效。

下一次，请尝试自己解决语法错误，它会比发布到堆栈溢出快得多。
