未在Gulp任务中定义$

我有以下package.json文件：

{
  "name": "ASP.NET",
  "version": "1.0.0",
  "devDependencies": {
    "gulp": "3.8.11",
    "gulp-inject": "1.5.0",
    "gulp-util": "3.0.6",
    "gulp-print": "1.1.0",
    "gulp-cssmin": "0.1.7",
    "gulp-uglify": "1.2.0",
    "gulp-load-plugins": "0.9.0",
    "del": "1.2.0",
    "wiredep": "3.0.0-beta",
    "jshint": "2.8.0",
    "jshint-stylish": "2.0.1"
  }
}

var gulp = require('gulp'),
    util = require('gulp-util'),
    print = require('gulp-print'),
    inject = require('gulp-inject'),
    del = require('del'),
    cssmin = require('gulp-cssmin'),
    jshint = require('gulp-jshint')
    uglify = require('gulp-uglify'),
    wiredep = require('wiredep').stream,
    bowerJson = require('./bower.json')
    gulp = require('gulp'),
    project = require('./project.json');

gulp.task('wiredep', function () {
    log('Placing Bower Components from ' + paths.bowerComponents + ' in ' + paths.layoutPage)
    return gulp
        .src(paths.layoutPage)
        .pipe(wiredep({
            bowerJson: bowerJson,
            directory: paths.bowerComponents,
            ignorePath: '../..'
        }))
        .pipe($.inject(gulp.src([
            paths.jsMain,
            paths.jsContent])))
        .pipe(gulp.dest(paths.layoutPage));
});

当我为bower.json运行此任务时，会出现以下错误：

[16:11:31]使用gulpfile C:\MyProject\src\MyProject\gulpfile.js
[16:11:31]正在启动“wiredep”…
[16:11:31]从./Bower\u Components/in../Views/Shared/\u Layout.cshtml放置Bower组件
[16:11:31]“wiredep”在5.7毫秒后出错
进程以代码1终止。
[16:11:31]引用错误：$未定义

为什么未定义$以及如何定义它

---

我尝试的是在package.json的devdependences中添加

“jquery”：“2.1.4”

。

通过阅读文件的gulpfile.js部分，我发现我不需要在它前面放

$

。需要直接注入和引用它。例如：

var inject = require('gulp-inject'),

gulp.task('inject', ['wiredep'], function () {
    log('Wire up the css and js into ' + paths.layoutPage);
    return gulp
        .src(paths.layoutPage)
        .pipe(inject(gulp.src([paths.js, paths.css], { read: false }), { ignorePath: project.webroot }))
        .pipe(gulp.dest(paths.layoutPagePath));
});

---

我认为直接使用

$

可以使用

var$=require（'jquery'）

并将jquery添加到package.json。如果我错了，请纠正我。

刚才我的项目也出现了这种现象。上次我发现gulp缺少一个名为“gulp load plugins”的插件； 在安装之后，我们应该声明它，将package.json中的所有插件放入$character；它是var$=require（'gulp-load-plugins'）（）
