RStudio 和 Travis CI 构建检查不匹配 (libudunits2.so)

Question

Travis CI 检测到我的RStudio 中的Build > Check 未找到的问题并发出问题我的lares 库（在Github 中作为laresbernardo/lares 找到）。根据 Travis CI 的说法，我最后一次“通过”提交实际上是一个错字更改，因此库的代码不应该是问题；因此，当我为库运行 devtools::check() 时，我会收到带有 0 个错误、警告或注释的漂亮 R CMD check succeeded 消息。

我也尝试过消息的建议和其他内容：

• 在终端 (macOS) 中运行 brew install udunits
• 通过 CRAN 使用 install.packages(units) 安装库
• 并通过 Github (dev) 使用 devtools::install_github("r-quantities/units", args="--configure-args='--with-udunits2-lib=/usr/local/lib'")
• 和devtools::install_github("r-quantities/units", args="--configure-args='--with-udunits2-include=/usr/include/udunits2'")

这是 Travis CI 日志的结尾，也可以在这里找到：https://travis-ci.org/laresbernardo/lares

  Configuration failed because libudunits2.so was not found. Try installing:
    * deb: libudunits2-dev (Debian, Ubuntu, ...)
    * rpm: udunits2-devel (Fedora, EPEL, ...)
    * brew: udunits (OSX)
  If udunits2 is already installed in a non-standard location, use:
    --configure-args='--with-udunits2-lib=/usr/local/lib'
  if the library was not found, and/or:
    --configure-args='--with-udunits2-include=/usr/include/udunits2'
  if the header was not found, replacing paths with appropriate values.
  You can alternatively set UDUNITS2_INCLUDE and UDUNITS2_LIBS manually.

我没有想法。是 stringi 或 units 库的变化吗？还是 Travis CI 问题？或者我的图书馆里有什么不同的设置？

解决了将以下内容添加到.travis.yml 文件的问题！我必须指定需要安装这个库。

addons:
  apt:
    packages:
      - libudunits2-dev

感谢 units 库的开发者 Iñaki Ucar 提供了非常有用的答案。
