Python ModuleNotFoundError:没有名为'；django_markdown2和x27；

我目前正在哈佛学习有关网络编程的课程。我需要将网站上的html页面转换为markdown，因此我将markdown安装到我的conda虚拟环境中，并将其添加到settings.py中已安装的应用程序中。但当我尝试运行服务器或迁移时，我遇到了一个问题，我得到了一个错误ModuleNotFoundError。我试图创建另一个虚拟环境，但效果并不理想。 提前谢谢你的提示

ModuleNotFoundError: No module named 'django_markdown2'

已解决 我必须在我的虚拟环境中安装pip install django-markdown2，而不仅仅是markdown2
