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

Question

特拉维斯CI检测并发布Build > Check中的RStudio找不到我的lares库（在Github中找到laresbernardo / lares）。根据Travis CI的说法，我的最后一次“通过”提交实际上是一个拼写错误，所以图书馆的代码不应该是问题;所以，当我为库运行devtools::check()时，我得到了带有0个错误，警告或注释的漂亮的R CMD check succeeded消息。

我已经尝试了消息建议和其他东西：

• 在终端（macOS）中运行brew install udunits
• 使用install.packages(units)通过CRAN安装库
• 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日志的结束，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。这是stringi或units图书馆的变化吗？还是特拉维斯CI问题？或者我库中的某些内容设置不同？

解决了将以下内容添加到.travis.yml文件中！我必须指定需要安装此库。

addons:
  apt:
    packages:
      - libudunits2-dev

感谢units图书馆开发人员IñakiUcar提供了非常有用的答案。
