当使用带有react-native-web的redux-saga时,我们得到一个错误`无

在我们的代码中,我有./sagas/index.js,其中包含：

function* mySaga() {
  console.log('my saga');
}

export default mySaga;

只要我在任何地方导入该文件(更不用说尝试调用该函数),我就会收到此错误：

Uncaught TypeError: Cannot read property 'mark' of undefined
    at Object../src/sagas/index.js (bundle.js:80385)
    at __webpack_require__ (bootstrap 029e2c2…:659)
    at fn (bootstrap 029e2c2…:85)

我认为它必须是我们的webpack中的东西所以我在这里包括：

const webpack = require('webpack');

const path = require('path');

module.exports = {
  devServer: {
    contentBase: path.join(__dirname,'build'),// enable HMR
    hot: true,// embed the webpack-dev-server runtime into the bundle
    inline: true,// serve index.html in place of 404 responses to allow HTML5 history
    historyApiFallback: true,host: '0.0.0.0',port: 3333
  },devtool: 'source-map',entry: [
    'webpack-dev-server/client?http://localhost:3333','webpack/hot/only-dev-server','react-hot-loader/patch',path.join(__dirname,'../index.web.js')
  ],module: {
    rules: [
      {
        test: /.js$/,include: [
          path.resolve(__dirname,"../node_modules/react-native-vector-icons"),path.resolve(__dirname,"../node_modules/react-native-elements"),"../node_modules/react-native-tab-view"),"../node_modules/react-native-side-menu"),"../node_modules/react-native-tab-navigator"),'../index.web.js'),'../src')

        ],loader: 'babel-loader?+cacheDirectory',query: {
            presets: ['es2015','stage-2','react','react-native','flow'],plugins: [
              'transform-flow-comments','transform-react-remove-prop-types'
            ]
        }
      },{
        test: /.(gif|jpe?g|png|svg)$/,"../node_modules/react-navigation"),"../src/assets/")
        ],loader: 'file-loader',query: { name: '[name].[hash:16].[ext]' }
      },{
        test: /.ttf$/,loader: "url-loader",// or directly file-loader
        include: path.resolve(__dirname,},]
  },output: {
    path: path.join(__dirname,filename: 'bundle.js'
  },plugins: [
    new webpack.HotModuleReplacementPlugin(),new webpack.NamedModulesPlugin(),new webpack.DefinePlugin({
      'NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'development'),'process.env': {
        NODE_ENV: JSON.stringify(process.env.NODE_ENV || 'development')
      },'__DEV__': JSON.stringify(process.env.NODE_ENV === 'development')
    })
  ],resolve: {
    modules: [
      path.join(__dirname,'..','node_modules')
    ],alias: {
      'react-native': 'react-native-web','react-navigation': 'react-navigation/lib/react-navigation.js',}
  }
};

有任何想法吗？？
