如何使用child-process.spawn从Gulp运行NG BUILD或禁用child-process.exec中的所有输出

标签: angular gulp

有一个类似的问题,例如Call "ng build" from inside a gulp task

我管理了我的Gulp以这种方式构建Angular以不溢出输出缓冲区

const child = require('child_process');

// Temporary solution, progress option makes angular more quiet, 
// but I need to shut it up completely

gulp.task('build', ['compile'], (cb) => {
  child.exec('ng build --progress false', (e, stdout, stderr) => {
    cb(e);
  });
});

不幸的是,这只能作为临时解决方案使用,因为只要Angular项目中的文件数量持续增长,child-process.exec的输出缓冲区很快就会溢出,所以我想要使用child-process.spawn从Gulp构建Angular,但每次执行此

// This is how I want to make it to work

gulp.task('build', ['compile'], () => {
  child.spawn('ng', ['build']);
});

我收到以下错误

Error: spawn ng build ENOENT
    at exports._errnoException (util.js:1018:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)
    at onErrorNT (internal/child_process.js:367:16)

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! cms.angular@1.0.0 server-start: `gulp`

有人知道从Gulp构建Angular 2项目的任何可靠方法吗?

刚刚找到答案How do I debug "Error: spawn ENOENT" on node.js?

最后,让它使用此包https://github.com/IndigoUnited/node-cross-spawn

const spawn = require('cross-spawn');

gulp.task('build', ['compile'], () => {
  spawn('ng', ['build'], { stdio: 'inherit' });
});

它就像一个魅力,但如果有人知道潜在的问题或缺点,请不要犹豫发表新的答案或评论。
