没有找到Django错误模块'Whitenoise‘

Question

我使用whitenoise在prod中部署静态文件，因此根据whitenoise的文档，建议在开发中也使用它。

因此，我遵循了文档，并将以下内容添加到我的settings.py文件中：

INSTALLED_APPS = [
    'whitenoise.runserver_nostatic',
    'django.contrib.admin',
    ...other
]

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    ...other
]

但是当我使用python manage.py runserver 0.0.0.0:8000运行服务器时，我会得到错误

ModuleNotFoundError:没有名为“whitenoise”的模块

ModuleNotFoundError: No module named 'whitenoise'

我使用pip freeze进行了检查，并安装了该模块(v5.0.1)和django 3.0.4。那我为什么要犯这个错误呢？

Answer 1

此问题将通过将白色模块安装到虚拟环境或全局解决。

pip install whitenoise
