Webpack和TypeScript:无法解析node.d.ts中的模块'child_process'

Question

我试图通过awesome- typescript -loader让webpack,typescript和react.js一起工作,但我经常遇到错误.

我在版本0.3.0-rc.2和webpack 1.8.9上使用了很棒的打字稿加载程序

这是我的webpack.config.js:

module.exports = {
    entry: './ui/index.ts',
    output: {
        path: __dirname + '/build-ui',
        filename: 'app.js',
        publicPath: 'http://localhost:8090/assets'
    },
    module: {
        loaders: [
            {
                test: /\.jsx$/,
                loader: 'jsx-loader?insertPragma=React.DOM&harmony'
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"
            },
            {
                test: /\.scss$/,
                loader: "style-loader!css-loader!sass-loader"
            },
            {
                test: /\.(png|jpg)$/,
                loader: 'url-loader?limit=8192'
            },
            {
                test: /\.ts$/,
                loader: 'awesome-typescript-loader'
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx', '.ts']
    }
};

当我运行webpack dev服务器时,我的index.ts看起来像这样:

alert('hello');

它声明了以下错误:

ERROR in ./ui/index.ts
/Users/..../typings/node/node.d.ts:29:12 
Subsequent variable declarations must have the same type.  Variable 'require' must be of type 'WebpackRequire', but here has type '{ (id: string): any; resolve(id: string): string; cache: any; extensions: any; main: any; }'.

当我放入参考路径时也一样.

当我尝试通过import React = require('react');它导入React.js 时:

ERROR in ./ui/index.ts
Module build failed: Cannot resolve module 'child_process' in /..../typings/node
    Required in /..../typings/node/node.d.ts

我从loader repo复制了node.d.ts文件,但仍然没有运气.

有没有人能够顺利完成这种组合？或者我应该使用不同的网络打包器？我真的很想让它与webpack一起工作.

您所缺少的只是一把钥匙target: 'node'。

这可以确保您要定位的环境是Node.js，而不是浏览器，因此将忽略本机依赖性。

最终配置：

module.exports = {
    entry: './ui/index.ts',
    target: 'node',
    output: {
        path: __dirname + '/build-ui',
        filename: 'app.js',
        publicPath: 'http://localhost:8090/assets'
    },
    module: {
        loaders: [
            {
                test: /\.jsx$/,
                loader: 'jsx-loader?insertPragma=React.DOM&harmony'
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"
            },
            {
                test: /\.scss$/,
                loader: "style-loader!css-loader!sass-loader"
            },
            {
                test: /\.(png|jpg)$/,
                loader: 'url-loader?limit=8192'
            },
            {
                test: /\.ts$/,
                loader: 'awesome-typescript-loader'
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx', '.ts']
    }
};
