**我已经安装了所有必要的模块,但是当我想要运行服务器时,则显示此消息
答案 0 :(得分:9)
我设法通过在github上使用这些包来修复相同的错误:
https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox
而不是Django-Mongodb设置页面上推荐的那些。此外,请确保使用每个的master
分支,以免遇到兼容性问题。如果您使用的是pip
,则可以单独pip install
以下各行,或者将它们放入您项目的requirements.txt
文件版本中:
git+https://github.com/django-nonrel/django-nonrel@master
git+https://github.com/django-nonrel/djangotoolbox@master
git+https://github.com/django-nonrel/mongodb-engine@master
然后运行
pip install -r requirements.txt
