未找到 Webpack 入口模块（按教程）

Question

在 codeacademy 上找到 this tutorial（链接到最后一页），决定尝试这种部署和配置 js 应用程序的现代方式（决定尝试 ReactJS）

按照说明逐步实施，但我发现了这个错误（当我尝试构建所有内容时）

ERROR in Entry module not found: Error: Can't resolve 'C:\Users\temp1\Documents\Learn\ReactJS\playaroundapp\index.html' in 'C:\Users\temp1\Documents\Learn\ReactJS\playaround' resolve 'C:\Users\temp1\Documents\Learn\ReactJS\playaroundapp\index.html' in 'C:\Users\temp1\Documents\Learn\ReactJS\playaround' using description file: C:\Users\temp1\Documents\Learn\ReactJS\playaround\package.json (relative path: .)

我的 webpack.config.js:

/** webpack required stuff */
var HTMLWebpackPlugin = require('html-webpack-plugin');

var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
        template: __dirname + 'app/index.html',
        filename: 'index.html',
        inject: 'body',
        minify: {
            removeComments: true,
            collapseWhitespace: true,
            removeAttributeQuotes: true
        },
        chunksSortMode: 'dependency'
    });

/** thing which traces stuff and transforms in teh better way with babel(?) */
module.exports = {
    entry: __dirname + '/app/index.js',
    module:{
        loaders:[
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader'
            }
        ]
    },
    output:{
        filename: 'transformed.js',
        path: __dirname + '/build'
    },
    stats: {
            colors: true,
            modules: true,
            reasons: true,
            errorDetails: true
    },
    plugins: [HTMLWebpackPluginConfig]     
};

以及package.json:

{
  "name": "playaround",
  "version": "1.0.0",
  "description": "just test prj",
  "main": "index.js",
  "scripts": {
    "build": "webpack",
    "start": "webpack-dev-server"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.6.1",
    "react-dom": "^15.6.1"
  },
  "devDependencies": {
    "babel-core": "^6.25.0",
    "babel-loader": "^7.1.1",
    "babel-preset-react": "^6.24.1",
    "html-webpack-plugin": "^2.29.0",
    "webpack": "^3.3.0",
    "webpack-dev-server": "^2.6.1"
  }
}

我不知道这里出了什么问题。怎么会？

Answer 1

看起来路径连接遗漏了一个斜杠，尝试

var HTMLWebpackPluginConfig = new HTMLWebpackPlugin({
        template: __dirname + '/app/index.html',
...

不过，可能更好的方法是像这样使用 path 实用程序模块 (https://nodejs.org/api/path.html)：

const path = require('path')
...
template: path.join(__dirname, 'app', 'index.html')
...

这使得路径连接不易出错，并且 OS 独立（反斜杠与斜杠 windows 与基于 *nix 的 os）
