run(command, args, options, emit) → {Promise}

The main arguments to this function are the same as passed to child_process.spawn

Name Type Description

the command to run

args Array

arguments for the command

options Object

      code: <exit code>,
      stdout: <standard output from the command>,
      stderr: <standard error from the command>
