R Shiny - Error: there is no package called ‘shinyjs’

My app works perfectly when I run it locally, but when I host it in shinyapps.io this error comes out:

An error has occurred

The application failed to start.

Error in value[3L] : there is no package called ‘shinyjs’ Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> Anonymous

I have two more apps online with the same ui.R and server.R layouts and both work fine. Even if I avoid the code involving shinyjs, it shows the app in the browser but the same error appears in the app log with the package openxlsx. The other two almost-identical apps working perfect got me completely lost.

In my experience, the issue happens in RStudio projects with a DESCRIPTION file, when the offending package (e.g. shinyjs) is NOT included in the Imports section of the DESCRIPTION file.

When you deploy your app on shinyapps.io the serve has to understand where the packages were installed from. The two most common sources of package installations probably are:

  • CRAN
  • Github

Looking at the documentation you see that Github packages must be installed with devtools. I have had the same issue you face because I had packages installed with remotes or pak, simply reinstall the packages locally you need using either install.packages for CRAN versions and devtools for dev versions and re-deploy:

install.packages("openxlsx")
# install.packages("devtools")
devtools::install_github("daattali/shinyjs")

I know this answer is late but in case is useful, here it is:

1.- Open a terminal and run: sudo R

2.- I installed shinyjs: install.packages("shinyjs", dependencies=TRUE)

3.- Create shinyjs directory: mkdir /usr/local/lib/R/site-library/shinyjs

4.- cd /usr/local/lib/R/site-library/shinyjs

4.- copy the shinyjs folder from the active username home R directory:

cp /home/username/R/x86_64-pc-linux-gnu-library/3.5/shinyjs/* -r .

Go to your web browsers and it will open your app.

Note. Be sure to change username for correct value and remember to set the privileges.
