$是不是定義腳本Gulp任務

嗨我想嘗試運行我的腳本任務吞嚥。我的腳本路徑定義如下：

scripts: { 
     coffee: [ 
      'app/assets/scripts/**/*.coffee' 
     ], 
     js: [ 
      'src/js/*', 
      'src/js/**/*' 
     ], 
     map: ['src/js/**/*.map'] 
    },

我原來的文件路徑位於根/ src目錄/ JS /我希望我的腳本被放置在他們的根/應用/資產/腳本內縮小的版本/。

我一飲而盡任務如下：

gulp.task('scripts', function() { 
    return gulp.src('app/scripts/**/*.js') 
     .pipe($.if('*.js', $.uglify({preserveComments: 'some'}))) 
     .pipe($.sourcemaps.init()) 
     .pipe($.concat('app.js')) 
     .pipe($.sourcemaps.write('./')) 
     .pipe(gulp.dest('app/assets/scripts')); 
}); 

But for some reason I keep getting this error 
[13:28:46] ReferenceError: $ is not defined 
    at Gulp.<anonymous> (C:\Users\Myuser\apps\myapp\gulpfile.js:165:9) 
    at module.exports (C:\Users\Myuser\apps\myapp\node_modules\gulp\node_

UPDATE

嘿，我覺得你都是對的。 $未定義，應該是$ = require('gulp-load-plugins')();。但是現在，我運行scripts，我得到以下錯誤：

[15:24:46] TypeError: undefined is not a function

同樣，另一個模糊的錯誤「undefined是不是一個函數」，這是明確的？缺少$功能嗎？

定義爲'$'在兩個腳本，並在這個問題上，這讓我相信你沒有定義'$'失蹤。 –

'$'應該是什麼？ – sma

謝謝你們，你是對的。請參閱上面的更新。 – HGB

您可能需要使用gulp-load-plugins包：

var $ = require('gulp-load-plugins')({lazy: true});
