Using spawn function with NODE_ENV=production

Question

I\'m currently trying to run process using spawn. What I am trying to run from shell is the following;

NODE_ENV=production node app/app.js

Answer 1

add shell option worked for me

gulp.task('xxx', function (callback) {
    process.chdir('xxx/');
    var spawn = require('child_process').spawn;
    var productionEnv = Object.create(process.env);
    // var jekyll = spawn('gulp', ['stylecheck'], {stdio: 'inherit', env: productionEnv});
    var jekyll = spawn('gulp', ['stylecheck'], {stdio: 'inherit', env: productionEnv, shell: true});

    jekyll.on('exit', function (code) {
        console.log(arguments);
    });
});
