Shiny deployment error

When I am trying to deploy my shiny app at shinyapps.io I get below error :

Has anyone come across this error. Appreciate if someone help me on how to resolve this. I am using R version 3.4.0

Thanks,

It looks like your app require NLopt, but shinyapps.io failed to install the package. The package installation seemed to be some shell script which may not work in the shinyapps.io server(because of permission etc).

Basically the deployment process scan your file and environment, then try to duplicate the dependency packages in the server. If you used CRAN version the server will also install CRAN version, which should not need build from source or running some shell script. If you used github version server will also try to use github version or build from source, which could have more dependency requirement.

Another possibility is the R package is just the interface and you need to install the actual library, which failed to be installed in server.

R packages will often rely on operating system packages to be installed on the server. If your application happens to use an R package that requires a system library that is not installed by default, please let us know by filing an issue, or a pull request, at shinyapps-package-dependencies
