Gulp TypeError：dest.on不是函数

Question

我正在尝试使用Gulp任务生成一个bundle.js文件

var gulp = require('gulp'),
    gutil = require('gulp-util'),
    wrench = require('wrench'),
    conf = require('./webpack.config'),
    webpack = require('webpack'),
    WebpackDevServer = require('webpack-dev-server');

// Webpack
gulp.task('wp', function() {
  return gulp.src('./assets/scripts/entry.js')
    .pipe(webpack(conf))
    .pipe(gulp.dest('./assets/build1'));
});

但是，当我尝试运行它时，我得到TypeError: dest.on is not a function：

这是文件夹目录：

Answer 1

发生错误是因为webpack与gulp流本身不起作用。当然，webpack()返回的对象并不包含特定于gulp的dest.on。

使用gulp-webpack或按照官方文档了解如何使用webpack with gulp

示例代码直接取自使用webpack-stream的官方文档：

var gulp = require('gulp');
var webpack = require('webpack-stream');

gulp.task('default', function() {
  return gulp.src('src/entry.js')
    .pipe(webpack())
    .pipe(gulp.dest('dist/'));
});
