set: Illegal option -o pipefail

[bieganski]

$ cat package.json | grep esm
/bin/sh: 1: set: Illegal option -o pipefail
  at file:///tmp/skrypt.mjs:3:8

after changing file index.mjs

let child = exec('set -euo pipefail;' + cmd, options)

to

    let child = exec('set -eu;' + cmd, options)

it works as expected.
My default shell is bash, I'm using Konsole 19.12.3

By default nodejs using /bin/sh

Add to beginning of file $.shell = ‘/bin/bash’

Bash now is used by default- fixed.
