dynamic terminal output of `exec` process not showing up

If I do something like exec('npm install'), I don’t see the spinner thing that npm shows in the console normally. Or for instance download progress meters that some commands print to the console. Is there a way to get them to show up with shelljs?

This is a duplicate of #251.

as a workaround, I managed to have my dynamic terminal using spawn with stdio

  const {spawn} = require('child_process');

  spawn(
    'my-command',
    ['any', 'options'],
    {stdio: [process.stdin, process.stdout, process.stderr]}
  );
