Webpack 2/Gulp/Typescript 生成意外令牌错误

Question

我正在尝试将使用 webpack 1 的项目更新为现在使用 webpack 2，但我遇到了两个无法解决的不同问题。

第一个问题是 webpack 似乎无法找到我的入口点，除非我在解析扩展数组中提供 '' 作为选项 - 根据我对文档的理解，对于 webpack 2，这应该不再需要了。我可以通过添加 '' 来解决该错误，但尝试加载文件时出现错误（“意外令牌。您可能需要适当的加载程序来处理此文件类型”）。我只在这篇文章中包含这两个问题，因为我认为它们可能是同一个问题的两个症状。

这是我正在使用的 gulp 文件的一部分：

const helpers = require('./config/helpers');

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

const buildNumber = process.env.buildNumber = helpers.buildNumber;


gulp.task('build-host-Debug', function (cb) {
    var webpackConfig_Host = require('./config/webpack-host.dev.js');

    return gulp
        .src([
            './src/app/entry1.ts'
        ], { base: 'src' })
        .pipe(webpackStream(webpackConfig_Host))
        .pipe(gulp.dest('./app'));
});

我将 webpack 配置拆分为两个文件 - 这是包含打字稿加载器的通用文件：

var webpack = require('webpack');
var helpers = require('./helpers');
var Visualizer = require('webpack-visualizer-plugin');

require('es6-promise').polyfill();

module.exports = {
    entry: {
        MyEntry1: './src/app/entry1.ts',
        MyEntry2: './src/app/entry2.ts'
    },
    output: {
        path: helpers.root('app'),
        filename: 'js/[name].js',
        chunkFilename: '[id].chunk.js'
    },

    resolve: {
        extensions: ['', '.tsx', '.ts', '.js'] 
    },
    module: {
        rules: [
            {
                test: /\.ts$/,
                exclude: [helpers.root('src', 'app/management'), helpers.root('src', 'app/main'), /node_modules/],
                use: [{
                    loader: 'awesome-typescript-loader'
                }]
            },
            {
                test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
                exclude: [helpers.root('src', 'app/management'), helpers.root('src', 'app/main'), /node_modules/],
                use: [{
                    loader: 'file-loader?name=images/[name].[ext]'
                }]
            }
        ]
    },
    plugins: [
        new Visualizer({
            filename: './stats-host.html'
        })
    ]
};

这是具有开发特定内容的继承文件（与我的生产文件略有不同）：

var webpack = require('webpack');
var webpackMerge = require('webpack-merge');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var commonConfig = require('./webpack-host.common.js');
var helpers = require('./helpers');

process.env.buildNumber = helpers.buildNumber;

module.exports = webpackMerge(commonConfig, {
    devtool: 'inline-source-map',
    module: {
        rules: [
            {
                test: /entry1\.scss$/,
                include: helpers.root('src', 'app/css'),
                use: [{ loader: 'file-loader?name=css/[name].css' }, { loader: 'sass-loader?sourceMap' }]
            },
            {
                test: /entry2\.scss$/,
                include: helpers.root('src', 'app/css'),
                use: [{ loader: 'file-loader?name=css/[name].css' }, { loader: 'sass-loader?sourceMap' }]
            }
        ]
    },
    plugins: [
        new webpack.DefinePlugin({
            'process.env': {
                'buildNumber': JSON.stringify(process.env.buildNumber)
            }
        })
    ]
});

如果我从已解析的扩展中删除 ''，则会收到此错误：

Error: Entry module not found: Error: Cannot resolve 'file' or 'directory' ./src/app/entry1.ts in W:\TestApp\
resolve file
  W:\TestApp\src\app\entry1.ts.tsx doesn't exist
  W:\TestApp\src\app\entry1.ts.ts doesn't exist
  W:\TestApp\src\app\entry1.ts.js doesn't exist
resolve directory
  W:\TestApp\src\app\entry1.ts\package.json doesn't exist (directory description file)
  W:\TestApp\src\app\entry1.ts is not a directory 

如果我离开 '' 我会收到此错误：

Error: ./src/app/entry1.ts

You may need an appropriate loader to handle this file type.

感谢任何人提供的任何帮助，因为我有点绝望，不想继续使用 webpack 1。

Answer 1

您的入口点不需要指定扩展名：

entry: {
    MyEntry1: './src/app/entry1',
    MyEntry2: './src/app/entry2'
},

Answer 2

我想通了。我的 gulp 任务必须将 webpack 对象传递给 webpackStream：

gulp.task('build-host-Debug', function (cb) {
    var webpackConfig_Host = require('./config/webpack-host.dev.js');

    return gulp
        .src([
            './src/app/entry1.ts'
        ], { base: 'src' })
        .pipe(webpackStream(webpackConfig_Host, webpack))
        .pipe(gulp.dest('./app'));
});
