I am building an R-package and have set up GitHub with Travis and Appveyor using the use_this package. Travis runs fine and the build is passing, but Appveyor fails when trying to install 'tibble'.
The package runs without problems on my computer (Windows 10).
I have no idea how to solve this, or even if it needs to be solved.
Any advice is much appreciated.
Output from Appveyor
