Gulp和browserify给出错误：无法从“C：....”中找到模块“jQuery”

Question

我收到的错误是：

错误：无法从'f:...\newstyle\assets\lib\helper\html\img\js'
在C:\users...\appdata\roaming\npm\node_module\browserify\node_module\srowserify\browser-resolve\node_module\srowser-resolve\lobers\lib\async.js:46:17
在进程Browser-resolve\node_module\resolve\lib\async.JS:188:17)
在加载时lib\async.js:22:47 at fsreqwrap.oncomplete（fs.js:153:21)

我的目录结构如下：

newstyle/assets/npm/index.js
newstyle/assets/npm/package.json
newstyle/assets/npm/gulpfile.js

newstyle/assets/lib/helper/html/img/js/img.module.js

require('@tschallacka/oc.foundation.controlutils');
// ====================== TROUBLE CAUSING LINE!! ==========================

var $ = require('jquery');

var controlUtils = require('@tschallacka/oc.foundation.controlutils');

'use strict';

var browserify = require('browserify');
var gulp = require('gulp');
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');
var uglify = require('gulp-uglify');
var sourcemaps = require('gulp-sourcemaps');
var log = require('gulplog');
var less = require('gulp-less');
var cssmin = require('gulp-cssmin');
var rename = require('gulp-rename');

gulp.task('javascript', function () {
  // set up the browserify instance on a task basis
  var b = browserify({
    entries: './index.js', // Source name
    debug: true
  });

  return b.bundle()
    .pipe(source('closure.js'))// Resulting filename
    .pipe(buffer())
    .pipe(sourcemaps.init({loadMaps: true}))
        // Add transformation tasks to the pipeline here.
        .pipe(uglify())
        .on('error', log.error)
    .pipe(sourcemaps.write('./'))
    .pipe(gulp.dest('../js/'));
});

gulp.task('watch', function () {
  gulp.watch('./*.less', ['less']);
});

gulp.task('less', function () {

  return gulp.src('./style.less')
    .pipe(less({
         relativeUrls: true
    }).on('error', function (err) {
      console.log(err);
    }))
    .pipe(cssmin().on('error', function(err) {
      console.log(err);
    }))
    .pipe(rename('closure.css'))
    .pipe(gulp.dest('../css/'));

});

当我运行这个没有引起麻烦的行时，一切都很好，它找到模块，它编译没有任何障碍。找不到模块没有问题。

但是当我需要这个脚本时，我从“父”脚本中要求作为测试的模块突然找不到了，尽管它应该仍然按字符串名在缓存中。

如果我按文件名“要求”文件，它确实可以工作，但这不太理想，因为这样我就经常需要检查目录嵌套。

var b = browserify({
    entries: './index.js', // Source name
    debug: true,
    basedir: __dirname
  });

Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
npm install -g npm-windows-upgrade
npm-windows-upgrade

更新的GULP：

解决方案相当简单，但不容易得出导致错误的原因，您必须在gulpfile.js中的browserify的'paths'变量中添加node_modules

// set up the browserify instance on a task basis
var b = browserify({
  entries: './index.js', // Source name
  debug: true,
  paths: ['./node_modules'] // <--- this line here
});
