Deploy R app in shinyapps.io - “Error Unhandled Exception"

Question

I'm trying to deploy my first app in shinyapps.io through RStudio but I can't. The console prompts this:

Preparing to deploy application...DONE
Uploading bundle for application: 337344...DONE
Deploying bundle: 1355635 for application: 337344 ...
Waiting for task: 523919702
  building: Processing bundle: 1355635
  building: Building image: 1368415
  error: Building package: rlang

########################## Begin Task Log ################################ ########################### End Task Log #################################

Error: Unhandled Exception: Child Task 523919707 failed: Error building image: Error building rlang (0.2.0). R version 3.5.0 currently unavailable
Ejecuci�n interrumpida

Any suggestion to solve this problem...? I've tried everything and I don't want to revert to the previous R version, in case this was the solution.

Thanks in advance.

Answer 1

For now, downgrade to R 3.4.4 would solve the problem.

Answer 2

Sadly it seems to be a problem with R 3.5. Shinyapps.io currently doesn't support this version. Probably you would go for a downgrade or wait until it gets the needed support.

I've found the same problem here: https://community.rstudio.com/t/error-deploying-to-shinyapps-io/7899
