Travis CI error while devtools::chech() doesn't

Here is the package in github.

As you can see in travis.yml, warnings are not treated as errors. When I do the check() in console, there are no errors. Here is the result:

0 errors ✓ | 4 warnings x | 1 note x

And here are the last lines of Travis CI.

What should I modify to get the it pass through Travis CI ?

Solution

I would seem that your package depends, at least, on raster and sf; and your script does not install them:

1: In i.p(...) : installation of package ‘terra’ had non-zero exit status
2: In i.p(...) : installation of package ‘units’ had non-zero exit status
3: In i.p(...) : installation of package ‘raster’ had non-zero exit status
4: In i.p(...) : installation of package ‘sf’ had non-zero exit status

The reason is most likely that you do not install the required system dependencies (GDAL, GEOS, ...). You need to add something like this to your system before installing these packages

sudo apt-get install libgdal-dev libproj-dev libgeos-dev libudunits2-dev netcdf-bin

I think that in a travis file that goes like this

addons:
  apt:
    packages:
      - libgdal-dev
      - libproj-dev
      - libudunits2-dev
      - netcdf-bin

You may prefer using github actions. See e.g. this workflow for terra
