添加站点扩展后，无法在Azure上运行R功能

Question

我对R来说是全新的，所以我必须错过一些简单的想法。

我试图了解如何将R代码作为Azure函数运行。我按照this示例进行了简化，我用

替换了script.r文件

print("Testing R")

但是当我运行此函数时，我在命令行中看到以下内容：

2017-09-01T14:07:52.388 Function started (Id=c031b7fc-1047-442e-8589-8cc6e7a96b48)

关于我缺少什么的任何想法？

Answer 1

我也遵循了这个例子，它在我身边工作得很好。

您似乎未在自己提供的the doc中的第5步中运行以下命令。

unzip -n D:\home\SiteExtensions\R-3.3.3x64\R-3.3.3.zip -d D:\home
