I try to use travis-ci to check whether my r package is correct. My package should import r pkg nloptr. And travis-ci will give the error in "r": "oldrel" branch. I show error here:

You should add the following to your .travis.yml as it will work in either container-based or standard infrastructures while the answer by Chaoran Hu only works for standard infrastructures:
addons:
apt:
packages:
- libnlopt-dev
See the travis docs for the why this answer will work more generally: https://docs.travis-ci.com/user/languages/r/#APT-packages
