My build is failing on Travis CI because uglify-js won't install. The relevant parts of the output log are below. I am installing nodejs and npm because this is a language: cpp build not a language: node_js build (its a C++ library with bindings to other languages, including some client side Javascript that needs minification).
$ sudo apt-get install nodejs npm --force-yes --assume-yes --fix-broken
$ sudo npm install -g uglify-js

Upon further testing, you need to run npm without sudo to solve your problem. This way you don't need to call apt-get beforehand.
