Django说-没有名为'blog'的模块 [英] Django says - No module named 'blog'

问题描述

将我的博客应用添加到settings.py的INSTALLED_APPS部分时，出现"ModuleNotFoundError: No module named 'blog'"错误.我确定这与我在INSTALLED_APPS下添加博客"应用程序的方式有关.当我从INSTALLED_APPS中删除博客"引用时，错误消失了.看来Django找不到我的博客应用程序的目录?

I am getting "ModuleNotFoundError: No module named 'blog'" error when add my blog app to the INSTALLED_APPS section of settings.py. I have determined that it has something to do with the way I have added the "blog" app under INSTALLED_APPS. When I remove the 'blog' reference from INSTALLED_APPS error goes away. It looks like that Django is unable to find directory for my blog app?

我做了另一件事，那就是使用:

I have done one thing differently and that is use:

python manage.py startapp blog /myproject

此处的区别是指定/myproject目录，而不使用:

Difference here is specifying the /myproject directory and not using:

python manage.py startapp blog

将其放置在根目录myproject下.我想避免在根文件夹中添加应用程序目录，以便保持井井有条.但是看起来Django不喜欢这个，或者我没有在INSTALLED_APPS部分正确地引用它?

Which will place it under root directory myproject. I wanted to avoid adding app directory in the root folder so i stay more organized. But it looks like Django does not like this or i am not referencing this correctly in the INSTALLED_APPS section?

我的项目目录如下:

myproject/
├── myproject
│   ├── __init__.py
│   ├── __pycache__
│   │   ├── __init__.cpython-36.pyc
│   │   ├── settings.cpython-36.pyc
│   │   ├── urls.cpython-36.pyc
│   │   └── wsgi.cpython-36.pyc
│   ├── blog
│   │   ├── __init__.py
│   │   ├── admin.py
│   │   ├── apps.py
│   │   ├── migrations
│   │   │   └── __init__.py
│   │   ├── models.py
│   │   ├── tests.py
│   │   └── views.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── db.sqlite3
└── manage.py

在我的settings.py内部，我已经设置了我的应用程序blog:

Inside my settings.py I have setup my app blog:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog',
]

推荐答案

Django需要能够导入您的应用程序，通常这意味着包括相对于根目录'myproject.blog'的完整路径.

Django needs to be able to import your application, usually this means including the full path relative to the root directory 'myproject.blog'.

您可以将<full_path_to_your_project>/myproject/myproject添加到PYTHONPATH，以便可以导入blog，但我不建议这样做

You could add <full_path_to_your_project>/myproject/myproject to PYTHONPATH so that you can import blog, but I would not recommend it
