Error in testthat about bayesiantools

[florianhartig]

I saw the messages, but no idea. If this fails on your local machine, don't you see a more detailed error message?

[florianhartig]

The devel build provides a bit more sensible error messages in the fail log https://travis-ci.org/florianhartig/BayesianTools/jobs/193218696

Ok, I'll try to figure out what's happening.

[florianhartig]

This is happening during the creation of the parallel executer in the setup. Seems the problem is

parallel::clusterCall(cl, packageFun, packages, dlls)

Maybe try this in isolation?

[stefan-paul]

Ok. Thanks for the hint!
Update: Found the problem and will fix it tomorrow in the morning!
