Shinyapps.io服务器是否未安装python？由于rPython软件包无法安装,因此需要安装python.如果答案是否定的,我觉得很奇怪,因为RStudio本身具有python support.

Shinyapps.io服务器是否支持python或有解决方法？我想要我发布的闪亮应用程序调用python脚本.

下面,即使在本地安装rPython时,在Shinyapps.io上安装rPython也会失败(显然我安装了python).

解决方法:

通常,在Shinyapps.io上安装了python,但这并不意味着rPython可以正常工作,或者您将能够执行脚本(取决于所需的python软件包).

尽管python本身可以工作,但我们不安装scipy / numpy,也不支持安装自定义python软件包.
