Gulp 4 Split Tasks Across Multiple Files Using Gul

2019-06-19 18:50发布

Using Gulp 4 and the recipe for splitting my tasks into multiple files using gulp-hub throws this error just from attempting to load the task files. The task file is super simple just wanted to test everything was working.

I found this reference on Undertaker on Github for the get function, but I really don't understand what they are trying to say, and it seems like gulp-hub is supposed to be doing the lifting.

Anyone else run into this and know how to solve it?

Gulp File

'use strict';

var gulp = require('gulp');

var HubRegistry = require('gulp-hub');

// Load some files into the registry
var hub = new HubRegistry(['gulp/tasks/*.js']); // only one file help.js

// Tell gulp to use the tasks just loaded
gulp.registry(hub);

Help Task - /gulp/tasks/help.js

'use strict';

var gulp = require('gulp');

gulp.task('help', []);

Error Thrown

$ gulp help
[01:36:37] Loading gulp\tasks\help.js

Update on 12.10.2016

I work with yeoman-fountainjs and in their package.json is the following dev-dependency definied, which works like a charm:

"gulp": "gulpjs/gulp#4ed9a4a3275559c73a396eff7e1fde3824951ebb",
"gulp-hub": "frankwallis/gulp-hub#d461b9c700df9010d0a8694e4af1fb96d9f38bf4",

I ran into the same error but it was because I failed to expose the tasks correctly to Gulp.

At first I was using CommonJS like this in my help.js file and getting the same error: exports.help = help;

So I changed it to a Gulp task and it worked: gulp.task("help", help);

You are probably running gulp-hub@0.8.0 which is the version that is currently published to npm and is designed for gulp 3.x.

For gulp 4.x you need to install gulp-hub from one of the development branches on GitHub. Currently there's 4.0 and registry-init.

The 4.0 branch doesn't work right now because it fails the registry validation of undertaker.

The registry-init branch seems to work however. You can install it like this:

npm uninstall gulp-hub
npm install --save-dev frankwallis/gulp-hub#registry-init
