The dbplyr package is installed and working on travis, why do I receive a message "there is no package called 'dbplyr'"?

Question

I'm testing an open source package called eutradeflows on travis-ci. I placed the following instruction in .travis.yml to install dbplyr:

r_packages:
  - dbplyr

I check that dbplyr works by calling one of its function with the following .travis.yml instruction:

  - Rscript -e "dplyr::check_dbplyr(); dbplyr::translate_sql(x +1)"

The dbplyr::translate_sql function does indeed return a result in travis see build 268358848 line 1162:

$ Rscript -e "dplyr::check_dbplyr(); dbplyr::translate_sql(x +1)"
<SQL> "x" + 1.0

But testthat tests that use other dbplyr functions inside my package complain, see build 268358848 line 1292:

"there is no package called 'dbplyr'"

The dbplyr is installed and working, how is that possible?

Answer 1

You just need to add package dbplyr to the DESCRIPTION file of your package.
