Answer 1

如果您使用的是venv（虚拟环境），则说明已安装的软件包未与您的项目关联，请确认您使用的是基本python 3.7，因为pip已将其软件包安装到。

Answer 2

Have you already add this app to your settings.py ? and make sure installed use right pip.

Answer 3

You have installed python2 package using pip install django-multiselectfield

Install it using pip3 install django-multiselectfield since you are using python 3.7.3

if you don't have pip3 ,

use apt-get install python3-pip

if you are using a virtual environment then you have to install in the virtual environment.
