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 [英] How to run NG BUILD from Gulp using child-process.spawn or disable all output in child-process.exec

问题描述

还有类似的问题，例如从一个大任务里面

There is a similar question like this Call "ng build" from inside a gulp task

我通过这种方式管理了Gulp来构建Angular，以免溢出输出缓冲区

I managed my Gulp to build Angular this way to not overflow the output buffer

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，这只能用作临时解决方案，因为只要Angular项目中的文件数量持续增长，child-process.exec的输出缓冲区迟早都会溢出，所以我想使用child -process.spawn从Gulp构建Angular，但是每次执行此操作

Unfortunately, this can be used only as a temporary solution because as far as number of files in Angular project continues to grow, soon or later output buffer of child-process.exec will overflow, so I'd like to use child-process.spawn to build Angular from Gulp, but every time I execute this

// 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)
    at _combinedTickCallback (internal/process/next_tick.js:80:11)
    at process._tickCallback (internal/process/next_tick.js:104:9)

有人知道从Gulp构建Angular 2项目的可靠方法吗?

Does anybody know any reliable way to build Angular 2 project from Gulp?

推荐答案

刚刚找到了答案

最后，使其与该软件包一起使用 https://github.com/IndigoUnited/node-交叉生成

Finally, made it working with this package https://github.com/IndigoUnited/node-cross-spawn

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

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

它的作用就像是一种魅力，但是，如果有人知道潜在的问题或不利之处，请不要犹豫，发表新的答案或评论.

It works like a charm, but if somebody knows about potential issues or downsides, don't hesitate to post a new answer or comment.
