Python和Django的：导入错误：没有模块名为local

Question

我试图运行该文件manage.py，其代码如下

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

if __name__ == '__main__':
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'config.settings.local')
try:
    from django.core.management import execute_from_command_line
except ImportError:
    # The above import may fail for some other reason. Ensure that the
    # issue is really that Django is missing to avoid masking other
    # exceptions on Python 2.
    try:
        import django  # noqa
    except ImportError:
        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?"
        )
    raise

# This allows easy placement of apps within the interior
# myproject directory.
current_path = os.path.dirname(os.path.abspath(__file__))
sys.path.append(os.path.join(current_path, 'myproject'))

execute_from_command_line(sys.argv)

用下面的命令：

python manage.py runserver_plus 0.0.0.0:8000

但我发现了以下回溯：

Traceback (most recent call last):
  File "manage.py", line 29, in <module>
    execute_from_command_line(sys.argv)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 364, in execute_from_command_line
    utility.execute()
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/core/management/__init__.py", line 308, in execute
    settings.INSTALLED_APPS
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/conf/__init__.py", line 56, in __getattr__
    self._setup(name)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/conf/__init__.py", line 41, in _setup
    self._wrapped = Settings(settings_module)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/conf/__init__.py", line 110, in __init__
    mod = importlib.import_module(self.SETTINGS_MODULE)
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named local

我不知道如何解释这个回溯修正错误。能否请您帮忙吗？

Answer 1

从您提供的代码，错误消息，我最好的猜测是，提供DJANGO_SETTINGS_MODULE模块路径是错误的：config.settings.local。

对于这个路径是有效的，你需要像下面的目录结构：

/
├── manage.py
├── config/
|   ├── __init__.py
|   ├── settings/
|   |   ├── __init__.py
|   |   ├── local.py

那是你的项目结构是什么样子（包括__init__.py文件）？如果没有，可以修改你的目录结构，或修改DJANGO_SETTINGS_MODULE的价值。
