ModuleNotFoundError：没有名为“ bootstrap4”的模块

我安装了bootstrap4

$ pip install django-bootstrap4

它被安装在这个目录中

C:\Users\trade\techpit-match-env\Lib\site-packages

Django似乎正在查看此目录

C:\Users\trade\Anaconda3\lib\site-packages\django

当我将'bootstrap4'放入INSTALLED_APPS =（'bootstrap4'）变量中然后运行时

$ python manage.py runserver

我得到这个错误

C:\Users\trade\techpit-match-env\Scripts\techpit>python manage.py runserver

ModuleNotFoundError: No module named 'bootstrap4'

如何解决此错误？我通过使用复制和粘贴在django文件夹中安装了bootstrap4，但这没有用。任何帮助将不胜感激。

谢谢！
