stdio pipe option returns an empty string

[pavitra-infocusp]

Stdio pipe option doesn't return the output. Using the inherit option reveals that the command executes successfully and logged in to the stdout.

Actual

import {execa} from 'execa';

const commandResult = await execa('npm', ['info', '@storybook/cli', 'version', '--json']);
console.log(commandResult);

❯ node testexec.js 
{
  command: 'npm info @storybook/cli version --json',
  escapedCommand: 'npm info "@storybook/cli" version --json',
  exitCode: 0,
  stdout: '',
  stderr: '',
  all: undefined,
  failed: false,
  timedOut: false,
  isCanceled: false,
  killed: false
}

The stdout value shouldn't be an empty string.

Expected

import {execa} from 'execa';

const commandResult = await execa('npm', ['info', '@storybook/cli', 'version', '--json'], {stdio:'inherit'});
console.log(commandResult);

❯ node testexec.js 
"8.0.9"
{
  command: 'npm info @storybook/cli version --json',
  escapedCommand: 'npm info "@storybook/cli" version --json',
  exitCode: 0,
  stdout: undefined,
  stderr: undefined,
  all: undefined,
  failed: false,
  timedOut: false,
  isCanceled: false,
  killed: false
}

Hi @pavitra-infocusp,

Thanks for reaching out.

When I run your first example on Ubuntu 23.10, Node 22.0.0, npm 10.6.0, Execa 8.0.1, I get the following result instead:

{
  command: 'npm info @storybook/cli version --json',
  escapedCommand: 'npm info "@storybook/cli" version --json',
  exitCode: 0,
  stdout: '"8.0.9"',
  stderr: '',
  all: undefined,
  failed: false,
  timedOut: false,
  isCanceled: false,
  killed: false
}

What is your OS, Node.js version, npm version and Execa version?
