travis-ci为r包构建

Question

我最近为我的在线课程构建了一个R包。然而，当我运行travis-ci build时，它由于以下错误而停止：

https://github.com/AnoushiravanR/fars

ERROR: configuration failed for package ‘gert’

* removing ‘/home/travis/R/Library/gert’

Error in i.p(...) : 

  (converted from warning) installation of package ‘gert’ had non-zero exit status

Calls: <Anonymous> ... with_rprofile_user -> with_envvar -> force -> force -> i.p

Execution halted

The command "Rscript -e 'deps <- remotes::dev_package_deps(dependencies = NA);remotes::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 .

Your build has been stopped.

如果你能给我一些如何通过这项测试的提示，我将不胜感激。我还在我的包上运行了R cmd check，我收到的唯一警告如下：

WARNING
  'qpdf' is needed for checks on size reduction of PDFs

但是，此签入也会暂停。

我也会留下我的github包地址：

我将这些代码行添加到我的.travis.yml中，并通过了travis构建：

addons:
  apt:
    packages:
      - libgit2-dev
