Question

运行时出现以下错误：

webpack watch

多个./main.js手表中的错误找不到模块：错误：无法解决＆＃39;观看＆＃39; in＆＃39; / Users / name / directory / src＆＃39; @ multi ./main.js观看

继承我的webpack.config.js文件

const path = require('path');

module.exports = {
  context: path.join(__dirname, 'src'),
  entry: [
    './main.js',
  ],
  output: {
    path: path.join(__dirname, 'www'),
    filename: 'bundle.js',
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        include: [
          path.resolve(__dirname, "src")
        ],
        exclude: /node_modules/,
        use: [
          'babel-loader',
        ],
      },
      {
        test: /\.scss$/,
        exclude: /node_modules/,
        use: [{
                  loader: "style-loader" // creates style nodes from JS strings
              }, {
                  loader: "css-loader" // translates CSS into CommonJS
              }, {
                  loader: "sass-loader" // compiles Sass to CSS
              }]
      }
    ],
  },
  resolve: {
    modules: [
      path.join(__dirname, 'node_modules'),
    ],
  },
};

这是我的package.json

{
  "name": "name",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "webpack-dev-middleware": "^1.10.1"
  },
  "devDependencies": {
    "babel-core": "^6.24.0",
    "babel-loader": "^6.4.1",
    "babel-preset-es2015": "^6.24.0",
    "babel-preset-latest": "^6.24.0",
    "babel-preset-react": "^6.23.0",
    "babel-preset-stage-2": "^6.22.0",
    "css-loader": "^0.27.3",
    "express": "^4.15.2",
    "node-sass": "^4.5.0",
    "react-helmet": "^4.0.0",
    "react-hot-loader": "^1.3.1",
    "sass-loader": "^6.0.3",
    "style-loader": "^0.14.1",
    "webpack": "^2.2.1",
    "webpack-dev-middleware": "^1.10.1",
    "webpack-dev-server": "^2.4.2"
  }
}

以下是我的main.js文件

import "./styles/stylesheet.scss";
import { Header } from "./components/headercomponent";

import React from "react";
import ReactDOM from "react-dom";
import { render } from "react-dom";

class App extends React.Component {
  render(){
    return (
    <div id="container">
      <Header/>
      <h1>hello world</h1>
    </div>
    );
  }
}

render(<App/>, window.document.getElementById("app"));

你知道我为什么会收到网络包错误吗？

传递给webpack CLI的参数将被视为入口点。您想使用--watch选项，而不是添加watch作为条目。正确的命令是：

webpack --watch
