deploying to shinyapps.io not recognising dependencies

[PaulC91]

Hi there,

I'm getting this warning message when trying to deploy a tutorial to shinyapps.io

In fileDependencies.R(tempfile) :
  Failed to parse /tmp/RtmpCboJHd/file40a4e0bd9fb ; dependencies in this file will not be discovered.

Which is resulting in the app failing to start with error message:

Error in value[[3L]](cond) : there is no package called ‘dplyr’

I have library(dplyr) in my tutorial setup chunk and have tried deploying from various computers (windows and linux) but the problem persists.

Thanks.

I'm getting this same message when trying to deploy a learnr tutorial over to shinyapps.io. Whenever I try to load in any R package, it gives this same issue, same error message, and same deploy log message.

Some packages that I tried: dplyr, ipumsr, ggplot2

EDIT: I should note that this occurs when I have code chunks where a "fill in the blank" is incorporated. For example, my exercise won't run if I have a code chunk with:

head(
  # Put your answer here
)

However, it will run if you have something there:

head(
  mtcars
)

Ah so it's the invalid R code caused by 'fill in the blank' sections that are the problem. Good to know.

The workaround I used was to have the learnr tutorial source files in an RStudio Cloud project I was also using for the workshop I was taking and then have each student launch the tutorial locally from their personal cloud space.

We are developing lessons for courses in a Stats program at NYU. Ran into the same issue when pushing to shinyapps.io. Hoping it gets resolved soon.

The issue is in packrat. Working on a fix in rstudio/packrat#551

[schloerke]

Now requiring a dev packrat version (which isn't used directly, just during deployment).

Please let me know if this dependency problem is not resolved with the last master branch.

Closing for now.

Yes, it's working now! Thanks for your help with this!
