A recent issue (#3401) suggests that when using Node <= 4 the application works (edit: as of 1.6.6, it no longer does), but plugins do not get installed. Upgrading to Node 6 solved that specific issue.

Maybe we should decide what is the minumim required Node version, and be clear about that.

installDeps.sh checks for Node >= 0.10:

but probably we should reconsider: Node 6 is currently the oldest supported version (going out of support on April 2019).

Using a more recent Node version could probably give us the possibility of modernizing the codebase, too (for example: async/await vs callbacks).
