Question

shinyapps.io服务器没有安装python吗？因为包rPython无法安装并且需要安装python。如果答案是否定的，我觉得很奇怪，因为RStudio本身有python support。

shinyapps.io服务器是否有python支持或是否有解决方法？我希望我发布的闪亮应用程序可以调用python脚本。

在shinyapps.io上的rPython安装下面失败，即使它安装并在本地完成时运行正常（我明显安装了python）。

Answer 1

一般来说，在shinyapps.io上安装了python，但这并不意味着rPython正常工作，或者你将能够执行你的脚本（取决于你需要的python包）。

虽然python本身可行，但我们不安装scipy / numpy，也不支持安装自定义python包。

rPython包无法在R Shiny shinyapps.io上安装
