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

Question

特拉维斯CI检测并没有被发现问题，Build > Check在RStudio我的lares图书馆（在Github上找到作为laresbernardo /拉雷斯）。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，因此库的代码应该不是问题；因此，当我devtools::check()为库运行时，我会收到R CMD check succeeded一条包含 0 个错误、警告或注释的好消息。

我已经尝试过消息建议的内容和其他内容：

• brew install udunits在终端 (macOS) 中运行
• 通过 CRAN 安装库 install.packages(units)
• 并通过 Github (dev) 与 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。是改变stringi还是units图书馆？还是 Travis CI 问题？或者我图书馆里的东西设置不同？

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

addons:
  apt:
    packages:
      - libudunits2-dev

感谢units库的开发人员 Iñaki Ucar提供了非常有用的答案。
