python - ModuleNotFoundError：没有名为“django_plotly

问题描述

我正在使用django_plotly_dash创建一个 Web 应用程序，这是一个将 Django、Plotly 和 Dash 组合到一个包中的模块。我遇到了一个问题，当我尝试使用 manage.py 文件运行命令时，出现错误ModuleNotFoundError: No module named 'django_plotly_dash'

从研究和回溯来看，问题似乎出在我的 settings.py 文件中，特别是带有静态文件/引导程序的文件，或者出在我的目录结构中。有更多经验的人是否看到我的结构或 settings.py 中导致此错误的任何问题

这是回溯消息：
