R Package is Passing R CMD check and devtools::check() locally, but errors out on Travis

[native-api]

Further in the log, under “R CMD check out logs”:

Error in loadNamespace(name) : there is no package called ‘usethis’

PyPI upload failed: "The description failed to render in the default format of reStructuredText"

That’s why I usually look at the raw log to find suspicious stuff. You never know under which fold the info you need might be.
