R Shiny Packaging: ERROR: unable to collate and parse R files for package ‘xx’

I am writing a Shiny app and have packaged the entire app into a package. Let's call this app/package fruit

Every time I made changes to the app, I would do the following:

library(devtools)
install()
library(fruit)
run_fruit_app()

I suspect that I messed up something while editing, now after I run install(), the following error messages pops up:

Running /Library/Frameworks/R.framework/Resources/bin/R CMD INSTALL \
  /var/folders/t6/v39yjp39xxxxxx/T//Rtmpxxx/fruit_0.1.0.tar.gz --install-tests

* installing *source* package ‘fruit’ ...
** using staged installation

 13. throw(new_process_error(res, call = sys.call(), echo = echo,  ...

 x System command 'R' failed, exit status: 1, stdout & stderr were printed

What could be potential source of errors? I did make sure that I did not forget to close a bracket, used a wrong bracket, or set things in the wrong working directory.

Any insights are much appreciated!

I updated the R software to R 4.3.2 and the problem was solved.

As mentioned in the comments, I recommend you do :

library(devtools)
check()
load_all()
run_fruit_app()

instead of installing the package every time you need to check something. Also, check() will tell you if there are problems with your code. I guess you have a call to library() somewhere in your code.

Finally, I also have a shiny app that is packaged. Just in case you need to check something, this is the link to the repo https://github.com/tomicapretto/sdeshiny

Good luck!
