I've had no luck in seeing any results appear in my iTerm2 while trying to use chalk which is a terminal string styling package. I followed all the steps in installing the package but I'm not seeing any colored string result appear when I run a basic console.log("hello"); in my chalk.js file.

Here is what I am doing.

#!/usr/bin/env node
var chalk = require('chalk');
chalk.blue('Hello world!');
console.log("hello");

Then in iTerm2 I run node chalk.js and I see no colored strings just plane old boring grey..

Anyone know what I'm doing wrong here?

• It should "just" work, since Iterm2 sets TERM to xterm by default, and that is what chalk checks for - see source github./sindresorhus/supports-color/blob/master/index.js – Thomas Dickey Commented Mar 31, 2015 at 10:22
• @ThomasDickey thax for your imput. Can you tell me exactly how you get it run "your set up" for chalk? – brent_white Commented Apr 2, 2015 at 4:07

Chalk functions return a string with the appropriate ANSI escape codes.

You need to console log the result of chalk calls.

console.log(chalk.blue("Hello, world!"));

If you still don't see any color, try running with the mand line argument --colors. If that still doesn't work, set an environment variable FORCE_COLOR=1.

If it still doesn't work, you're wele to file a bug report!
