How to set child process' environment variable in Makefile

Question

I would like to change this Makefile:

SHELL := /bin/bash
PATH  := node_modules/.bin:$(PATH)

boot:
    @supervisor         \\
      --harmony         \\

Make variables are not exported into the environment of processes make invokes... by default. However you can use make's export to force them to do so. Change:

test: NODE_ENV = test

to this:

test: export NODE_ENV = test

(assuming you have a sufficiently modern version of GNU make >= 3.77 ).
