Question

我已经搜遍了这个问题的解决方案，并且没有任何运气。我试图弄清楚为什么我会收到以下错误：

ERROR in ~/node_modules/@types/react-router/lib/applyRouterMiddleware.d.ts
(4,43): error TS2305: Module ‘”~/node_modules/react/react".export=' has no exported member 'Props'.

有数百个与大多数引用未导出属性的@types定义文件相关。

我在这里使用webpack进行构建过程。这是 webpack.config.js ：

module.exports = {
  target: 'node',
  devtool: 'source-map',
  devServer: { historyApiFallback: true },
  context: root(),
  entry: './src/index.tsx',

  resolve: {
    extensions: [ '', '.js', '.ts', '.tsx', '.scss', '.css' ],
    root: root('src'),
    alias: {
      //inject environment variables via aliases
      conf: isProd() ? './conf/production.js' : './conf/development.js',
    },
  },

  output: {
    filename: 'bundle.js', //the output js file
    path: root('dist'), //build directory
    libraryTarget: 'umd',
  },

  externals: {
    fs: 'fs',
    winston: 'winston',
    system: '{}',
    file: '{}',
  },

  module: {
    loaders: [
      {
        test: /\.tsx?$/,
        loader: 'ts-loader',
      },
      {
        test: /\.(s)?css$/,
        loader: extractCSS.extract('css-loader!postcss-loader'),
      },
      {
        test: /\.json$/,
        loader: 'json-loader', //reference by npm module or path to loader file
      },
      {
        test: /\.jpe?g$|\.gif$|\.png$|\.svg$|\.woff$|\.eot$|\.ttf$/,
        loader: 'file-loader?name=assets/images/[sha512:hash:base64:7].[ext]',
        exclude: root('node_modules'),
      },
    ],
  },

  plugins: [
    extractCSS,
    new StaticHTMLPlugin(
      'bundle.js',
      root('src/Routing.tsx'),
      [ '.png', '.gif', '.jpg', '.jpeg', '.css', '.scss' ]
    ),
  ],
}

以下是 package.json 的副本：

"devDependencies": {

}

关于可能会发生什么的任何想法？我对React lib本身并不十分熟悉。我没有看到直接导出的属性，但我还没有深入挖掘lib，看看它们是否以其他方式导出。

如果React lib与@ types / react类型之间存在不一致，我会感到很奇怪，我是唯一遇到此问题的人。这就是为什么我倾向于这是一种配置问题。

我也在tsc上运行该项目，似乎实际上正确地构建了一些东西。虽然b / c tsc在控制台中输出了数千条垃圾线，但很难确定。

感谢。

所以，这里的解决方案是将tsconfig.json道具，allowJs设置为false：

"compilerOptions": {
  "allowJs": false
}

现在，我在这里的问题是为什么？谁能解释一下？

React没有导出的成员＆＃39;道具＆＃39;
