v3.0.25 npm install failing on phantomjs

macOS 10.12.6 node -v v8.4.0 npm -v 5.4.1

Updated to latest version of backstopjs which fails at phantomjs. Relevant portion of log below.

I’ll downgrade for now, but any idea what might be causing this?

I fixed it by setting user/group of /usr/lib/node_modules/ (OS: Ubuntu 17.04) to my user and install BackstopJS globally without sudo:

$ sudo chown -R $(id -u):$(id -g) /usr/lib/node_modules/
$ npm install -g backstopjs

No BackstopJS problem, but a npm/phantomJS one…
