I have developed packages in R previously using Travis CI and codecov, but never packages that interfaced with Stan. I am in the beginning stages of one now (repo: https://github.com/wjakethompson/lcdm), but for some reason the code coverage always fails, while everything else succeeds. Here is the error I get on Travis:
Error in file(con, "r") : cannot open the connection Calls: <Anonymous> -> package_coverage -> add_hooks -> readLines -> file In addition: Warning messages: 1: In utils::install.packages(repos = NULL, lib = tmp_lib, pkg$path, : installation of package ‘/home/travis/build/wjakethompson/lcdm’ had non-zero exit status 2: In file(con, "r") : cannot open file '/tmp/RtmpYQaU1s/R_LIBS2ed17a919085/lcdm/R/lcdm': No such file or directory Execution halted
It appears that the installation is failing, but I’m not sure why that would be.
Here is the
.travis.yml file: https://github.com/wjakethompson/lcdm/blob/master/.travis.yml
And here is the build history: https://travis-ci.org/wjakethompson/lcdm/jobs/280171037
Any help would be greatly appreciated!
