Add "npm install" to prepare-dev.py
Review Request #7990 — Created Feb. 23, 2016 and submitted
All my pipeline/media changes require lessc and babel to be installed in the
local environment. This change adds the relevant command to prepare-dev to try
to prevent some of the inevitable confusion.
Removed my
node_modules
directory and ran prepare-dev.py. Saw that everything
got installed correctly.
