Travis-CI error: installing nloptr pkg (r pkg check)
我尝试使用travis-ci检查我的r包是否正确。我的包应该导入 r pkg nloptr。而 travis-ci 会在 "r": "oldrel" 分支给出错误。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 nloptr 所需要的。 （travis-ci 无法通过给定的 url 下载 nlopt。）幸运的是，我们可以通过将此代码添加到 .travis.yml 来告诉 travis-ci 另一种方式文件，这有助于 travis-ci 通过另一种方式安装 nlopt。
apt_packages:
- libnlopt-dev
现在，travis-ci可以很好地为您服务！
您应该将以下内容添加到您的 .travis.yml 中，因为它可以在 container-based 或标准基础架构中使用，而胡超然的答案仅适用于标准基础架构：
addons:
apt:
packages:
- libnlopt-dev
