Lerna --stream removing chalk colors log

Expected Behavior

Chalk colors should be shown in the terminal. That’s the whole point of using chalk in the first place.

Current Behavior

lerna run --stream command gives below kind of output. All the colors go away!! 😦

Possible Solution

Please allow colors in lerna run --stream

Steps to Reproduce (for bugs)

1. Run node filename_having_chalk_logs.js It’ll print proper chalk logs
2. Now run the same command through lerna run <npm command> --stream, it won’t show the colors

lerna.json

<!-- Please paste your `lerna.json` here -->
{
  "packages": [
    "packages/**"
  ],
  "npmClient": "yarn",
  "useWorkspaces": true,
  "version": "independent"
}

Context

I’m running a Koa server to proxy api requests coming from my react app to relay them to the backend servers, I’ve applied morgan logs for intercepting requests and spent lot of time in making the output colorful, but sadly all in vain cause of lerna. Please help.

FORCE_COLOR=1 should also fix the problem for chalk 😃
