我尝试使用 travis-ci 来检查我的 r 包是否正确。我的包应该导入 r pkg nloptr。并且 travis-ci 将在 "r": "oldrel" 分支中给出错误。我在这里显示错误：

所以，问题是 travis-ci 不知道如何安装这个nlopt，这是 r pkg 所需要的nloptr。（travis-ci 无法nlopt通过给定的 url 下载。）幸运的是，我们可以通过将这段代码添加到.travis.yml文件中来告诉 travis-ci，这有助于 travis-ci 以另一种方式安装 nlopt。

apt_packages:
  - libnlopt-dev

现在，travis-ci 可以很好地为您服务！

您应该添加以下内容，.travis.yml因为它将在基于容器或标准基础架构中工作，而 Chaoran Hu 的答案仅适用于标准基础架构：

addons:
  apt:
    packages:
      - libnlopt-dev

请参阅 travis 文档，了解为什么这个答案更普遍：https ://docs.travis-ci.com/user/languages/r/#APT-packages
