When the `make requirements` command trying to install phantomjs, it shows this error: ... info lifecycle phantomjs@1.9.20~install: Failed to exec install script ... verbose stack Error: phantomjs@1.9.20 install: `node install.js` verbose stack Exit status 1 ... And this solves that problem in my Ubuntu 16.04: sudo apt install nodejs-legacy
