How to fix "Task is not in your gulpfile" error when using npm link?
提问by zedix
We have a bunch of applications sharing common gulp logic, so we made a gulp plugin that contains a bunch of custom tasks.
我们有一堆共享通用 gulp 逻辑的应用程序，所以我们制作了一个包含一堆自定义任务的 gulp 插件。
However we'd like to avoid installing gulp+our plugin (along with half the internet) for each of the applications we develop.
但是，我们希望避免为我们开发的每个应用程序安装 gulp+我们的插件（以及一半的互联网）。
Ideally, I'd like to do:
理想情况下，我想做：
npm install -g gulp
npm install -g <our gulp plugin>
Then for each app, we'd simply have to do:
然后对于每个应用程序，我们只需要做：
npm link gulp
npm link <our gulp plugin>
Although this works, the problem is gulp no longer recognizes any of our custom gulp tasks. Any gulp command I run results in:
尽管这有效，但问题是 gulp 不再识别我们的任何自定义 gulp 任务。我运行的任何 gulp 命令都会导致：
[15:16:51] Using gulpfile /workspace/my-app/gulpfile.js
[15:16:51] Task 'dev' is not in your gulpfile
[15:16:51] Please check the documentation for proper gulpfile formatting
The 'dev' tasks is in my gulp plugin, why isn't it finding it? My gulpfile.js only has this:
“开发”任务在我的 gulp 插件中，为什么找不到它？我的 gulpfile.js 只有这个：
var gulp = require('gulp');
var mygulpplugin = require('mygulpplugin');
The exact same process works when gulp + the plugin is installed locally. Any ideas why?
当 gulp + 插件安装在本地时，完全相同的过程起作用。任何想法为什么？

Figured it out. Added the following line at the bottom of my module:
弄清楚了。在我的模块底部添加了以下行：
module.exports = gulp;
And my gulpfile in each module looks like this:
我在每个模块中的 gulpfile 看起来像这样：
var gulp = require('gulp');
var mygulpplugin = require('mygulpplugin');
gulp.tasks = mygulpplugin.tasks;

Alternatively to the accepted answer, you can do it the way that was popular in grunt times, where you inject gulp to the plugin:
除了已接受的答案，您还可以采用在咕噜声中流行的方式，将 gulp 注入插件：
In plugin:wrap everything with:
在插件中：用以下内容包装所有内容：
module.exports = function(gulp) {
gulp.task('foo', function () {
...
})
...
}
and remove require('gulp')from the plugin's file.
并require('gulp')从插件文件中删除。
In gulpfile that depends on pluginyou then do:
在依赖插件的 gulpfile 中，您可以执行以下操作：
var gulp = require('gulp');
require('my-gulp-plugin')(gulp)
That way
那样
- you can have multiple plugins in the main gulpfile, because you don't override
gulp.tasks. - plugins don't have to declare
gulpapackage.jsondependency in each of the plugins (less work fornpm install)
- 您可以在主 gulpfile 中有多个插件，因为您不会覆盖
gulp.tasks. - 插件没有宣布
gulp一个package.json在每个插件的依赖（较少的工作npm install）
