Error installing fable.prophet

Hi - I'm getting this error installing fable.prophet. I have fabletools 0.1.1.9000 installed.

* installing *source* package ‘fable.prophet’ ...

Looks as if this is due to a permissions problem specific to your system. Using the CRAN version of fabletools should be sufficient, could you try this?

Thanks for the suggestion. I'm using RStudio within IBM Watson Studio, and have tried re-installing all packages from CRAN (including fabletools 0.1.1, but then get the same message for fable.prophet. I've raised a ticket with the Watson Studio team so will update if they have a fix.

Watson Studio Close notes:

The R version used in Watson studio is 3.6.1 and the platform in which it runs is Debian GNU/Linux 9. "fable.prophet" package has a maximum version compatibility of R 3.6.0 for Linux based OS. You can check the version compatibilities of the package here : https://github.com/mitchelloharawild/fable.prophet/blob/master/cran-comments.md . I would recommend you to open an issue with the fable.prophet team/github to support R 3.6.1 for Linux based OS.

I'm currently running R 3.6.1 on a Linux based OS without issue, and the CI is testing across a variety of R versions and operating systems.

From the error above:

Failed to create bus connection: Permission denied Error: package or namespace load failed for ‘fabletools’: .onLoad failed in loadNamespace() for 'anytime', details: call: system("timedatectl", intern = TRUE) error: (converted from warning) running command 'timedatectl' had status 1

This would suggest to me that IBM Watson Studio does not allow you to run system("timedatectl", intern = TRUE), which is causing the anytime package to error. Could you try running system("timedatectl", intern = TRUE) yourself and see what you get?

Thanks Mitchell. Ran per below. Will raise with the Watson team:

system("timedatectl", intern = TRUE)
Failed to create bus connection: Permission denied
character(0)
attr(,"status")
[1] 1
Warning message:
In system("timedatectl", intern = TRUE) :
  running command 'timedatectl' had status 1

Closing as this is not an issue with the package. Good luck with the Watson team.
