node.js - 模块构建失败 : ReferenceError: [BABEL]/app/src/index. js : Unknown option:/app/node_modules/react/react. js.Children

Question

我的项目失败，并在 Heroku 上出现标题中的错误消息，但它可以在本地运行。

这是我的webpack.config.js:

module.exports = {
  entry: [
    './src/index.js'
  ],
  output: {
    path: __dirname,
    publicPath: '/',
    filename: 'bundle.js'
  },
  module: {
    loaders: [{
      test: /\.js$/,
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['react', 'es2015', 'stage-0']
      }
    }]
  },
  resolve: {
    extensions: ['.jsx', '.js']
  },
  devServer: {
    historyApiFallback: true,
    contentBase: './'
  }
};

这是package.json:

{
  "main": "index.js",
  "scripts": {
    "start": "node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js",
    "test": "mocha --compilers js:babel-core/register --require ./test/test_helper.js --recursive ./test",
    "test:watch": "npm run test -- --watch"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-preset-es2015": "^6.1.18",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-1": "^6.24.1",
    "chai": "^3.5.0",
    "chai-jquery": "^2.0.0",
    "jquery": "^2.2.1",
    "jsdom": "^8.1.0",
    "mocha": "^2.4.5",
    "react-addons-test-utils": "^0.14.7"
  },
  "dependencies": {
    "axios": "^0.17.1",
    "lodash": "^3.10.1",
    "react": "^0.14.3",
    "react-dom": "^0.14.3",
    "react-redux": "4.3.0",
    "react-router": "^2.0.1",
    "react-router-dom": "^4.0.0",
    "redux": "^3.0.4",
    "redux-form": "^6.6.3",
    "redux-promise": "^0.5.3",
    "validator": "^9.1.2",
    "webpack": "^3.8.1",
    "webpack-dev-server": "^2.9.4"
  }
}

我进行了一些挖掘，试图找到答案，但没有出现在一台机器上工作，而在另一台机器上不工作的情况。

更新1

这是index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import { BrowserRouter, Route, Switch } from 'react-router-dom';
import promise from 'redux-promise';

import reducers from './reducers';

import LoginForm from './components/login_form';

const createStoreWithMiddleware = applyMiddleware(promise)(createStore);

ReactDOM.render(
  <Provider store={createStoreWithMiddleware(reducers)}>
      <BrowserRouter>
        <div>
          <Route path="/" component={LoginForm} />
        </div>
      </BrowserRouter>
  </Provider>
  , document.querySelector('.container'));

** 更新 2 **我尝试将 webpack loader 配置对象中的 test 属性的 jsx 更改为 js，但没有帮助。我删除了 stage-1 但它仍然失败。

Answer 1

此问题已得到解决:

1. 从 webpack 配置文件中删除了 module.query 和 resolve。
2. 将依赖项从 devDependency 移至 dependency(heroku 是生产环境，因此它不会下载 devDependencies，这也不会下载)对我来说很有意义!)
