Phantomjs dependency fails to install when using NPM

[sils]

sils@lsnmb ~ % sudo npm install -g gitlab-time-tracker               
/usr/bin/gtt -> /usr/lib/node_modules/gitlab-time-tracker/src/gtt.js

> phantomjs-prebuilt@2.1.16 install /usr/lib/node_modules/gitlab-time-tracker/node_modules/phantomjs-prebuilt
> node install.js

Considering PhantomJS found at /usr/bin/phantomjs
Looks like an `npm install -g`
Could not link global install, skipping...

I removed some unused PDF related modules and bumped the version of the underlying markdown-pdf library. Unfortunately I cannot reproduce the issue, but this could solve it. Could you try again using version 1.7.13?
