doesn't show child process spinner

[tjx666]

if I run npx i18n pull --workspaces in zsh, will show spinner:

but using following code will not:

export async function execWithOutput(command: string, cwd?: string) {
    const subprocess = execaCommand(command, {
        cwd,
        shell: true,
        stdin: 'inherit',
        env: { FORCE_COLOR: 'true' },
    });
    subprocess.stdout?.pipe(process.stdout);
    subprocess.stderr?.pipe(process.stderr);
    await subprocess;
    return subprocess;
}

execWithOutput('npx i18n pull --workspaces')

Hi @tjx666,

Thanks for reaching out, but it seems like this issue might be more related to how process execution works in general, as opposed to Execa itself.

In particular, this might be related to the TTY being non-interactive, due to using pipe() instead of stdout: 'inherit' or stderr: 'inherit'. Many spinner libraries are disabled by default when they detect that stdout or stderr is running in a not interactive TTY (such as in a CI).

However, this is not related to Execa itself, as you'd experience the same issue using child_process.spawn() directly.

Also, we would need a GitHub repository to reproduce this specific issue, since this involves a few implied dependencies and setup.
