My cron-enabled builds started failing in the past day or so due to a missing package, devtools, that
is listed in my DESCRIPTION file and used to be installed as expected. Comparing logs with the previous build that worked I see that instead of devtools the remotes package is installed.
An example previous working build: https://travis-ci.org/ShawHahnLab/chiimp/jobs/506519381
A new failing build: https://travis-ci.org/ShawHahnLab/chiimp/jobs/518494175
(This may be related to https://travis-ci.community/t/2940 though I don’t have the error given there.)
