Using exec does not terminate the command process

Description of the bug:

Using exec does not terminate the command process

Example ShellJS command to reproduce the error:

const scripts = {
  dev: 'vite',
  predev:'scripts'
};


exec('dev', function (code, stdout, stderr) {});

When I execute dev, predev will be executed first according to the life cycle of npm. I have some logical judgments in predev. If I make an error, I will exit(1) the terminal command process, but when I use shelljs.exec('dev'), When predev is executed first, the command process will not be interrupted even if there is an error
