R包：travis CI错误

Question

我收到来自Travis-CI的名为OPWpaper的R包的以下错误。任何人都可以告诉我如何解决这个问题？

"Rscript -e 'deps <- devtools::dev_package_deps(dependencies = NA);devtools::install_deps(dependencies = TRUE);if (!all(deps$package %in% installed.packages())) { message("missing: ", paste(setdiff(deps$package, installed.packages()), collapse=", ")); q(status = 1, save = "no")}'" failed and exited with 1 during .

请注意，我的.travis.yml文件是：

# R for travis: see documentation at https://docs.travis-ci.com/user/languages/r
language: r
sudo: false
cache: packages

  - devel

warnings_are_errors: true

  - Rscript -e 'covr::codecov()'
