ASP.NET MVC-R IIS部署

Question

My app consumes r.net library. it works fine in the development pc (as always) when i run it from visual studio. Now when I deploy it in the production server under IIS. It throws

Error: Package or namespace load failed for 'RODBC'

in my c# code i have

engine.Evaluate("library(RODBC)")

in the server, in my environment variable for 'Path' I have "C:\\Program Files\\R\\R-3.2.2\\bin\\x64" . Doesn't help. I also gave permission (to all) in the library folder- no luck.

When I run the r script in R-Studio in the server, it just works fine. But when i run my web app, it doesn't work.

any help???

Answer 1

this one finally helped me solving it.

1. set R_HOME as "C:\\Program Files\\R\\R-3.1.2",
2. R_PATH as "C:\\Program Files\\R\\R-3.1.3\\bin\\i386" (or x64, depends on 32bit or 64bit process), add them to system PATH and add bit to system PATH
3. restart IIS before you try again (iis reset)
