`npm install` fails

[Julian Kniephoff]

Running npm install in a fresh clone of the Eve repository fails for me with the following message:

npm WARN prepublish-on-install As of npm@5, `prepublish` scripts will run only for `npm publish`.
npm WARN prepublish-on-install (In npm@4 and previous versions, it also runs for `npm install`.)
npm WARN prepublish-on-install See the deprecation note in `npm help scripts` for more information.

I tested this with a fresh clone on macOS Sierra 10.12.3 and on Ubuntu 16.10. Both run the most recent version of node and npm that I could reasonably get (7.6.0 and 4.1.2 respectively). This also happenes with the 0.2.3 source code for me under the same systems, though.
