Spatial packages and TravisGIS · Code · rstats sf · simple features · tmap · travis
A number of
R spatial libraries have been updated in the last couple of weeks, and this has played havoc with my Travis-CI build.
I had still been using Ubuntu Trusty with Travis which uses old versions of libraries like
rgeos, so I needed to move to updated versions of these.
sf has now become a dependency for a number of spatial packages like tmap, and this uses
libudunits2-dev which isn’t installed by default.
To solve all these problems at once as simply as possible, I switched to using a docker container within Travis so I could use an Ubunutu 16.04 (‘Xenial’) build.
This meant I was able to upgrade to more up-to-date versions of most packages.
I installed the
ubuntugis-unstable ppa to use the most recent versions of
I finally installed
libudunits2 so I could update
The docker container is a bit slower (6 minutes vs 3 minutes) but will hopefully speed up with caching.
.travis.yml looked like this (I’ve removed my notification options and coverage report token for clarity):
