无法点子安装 django-dash

Question

我安装了django和dash，但没有安装django-dash。有什么想法为什么不起作用吗？

我都试过了：

pip install django_plotly_dash
pip install django-dash

命令提示符错误：

ERROR: Could not find a version that satisfies the requirement django_plotly_dash (from versions: none)
ERROR: No matching distribution found for django_plotly_dash

新错误：

它不是下划线，而是短划线。

pip install --trusted-host pypi.python.org  django-plotly-dash
