我在项目中安装了django_pyowm，但是django拒绝迁移模型。提到我还没有安装模块的事实。
下面我得到此错误输出：
>>> python3 manage.py makemigrations django_pyowm
Traceback (most recent call last):

首先，我试图找出该库是否安装正确，然后检查了pip和pip3版本。
Python 3.5.2 (default, Nov 12 2018, 13:43:14)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import django_pyowm
然后
>>> pip3 freeze
certifi==2019.3.9
chardet==3.0.4
Django==1.10.5
django-leaflet==0.24.0
django-pyowm==0.2.0
geojson==2.4.1
idna==2.8
pkg-resources==0.0.0
psycopg2==2.7.7
pyowm==2.10.0
requests==2.21.0
urllib3==1.24.3
我也阅读了这个主题，但是它没有帮助我： pip is not installing pyowm correctly for some reason
我还纠正了settings.py
INSTALLED_APPS = [
'django_pyowm',
]
