NodeJS无法转到该文件夹​​以执行child_process.spawn中的命令

Question

To start WebPack (which is in the parent folder) I use Gulp, but as soon as I try to go to the parent folder in the path, I get an error.

Gulp

var spawn = require('child_process').spawn;

gulp.task('_Scada2', function (done) {
  spawn('webpack', [], { cwd: '../../Scada.Web/' })
    .on('close', done);
});

get an error

[14:20:47] '_Scada2' errored after 4.47 ms
