webpack - 注意不工作

webpack --watch不起作用,但是webpack没有,当我在js中编辑一些更改时,观察者不会在我的DOM(html)中进行任何更新,所以我将不得不重新启动(再次执行webpack)以便它将更新更改。

可能有错误的代码:

的package.json:

`{
  "name": "samplereact",
  "version": "1.0.0",
  "main": "webpack.config.js",
  "dependencies": {
    "babel-loader": "^6.2.4",
    "babel-plugin-add-module-exports": "^0.1.4",
    "babel-plugin-react-html-attrs": "^2.0.0",
    "babel-plugin-transform-class-properties": "^6.9.0",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.5.0",
    "babel-preset-stage-0": "^6.5.0",
    "core-js": "^2.4.0",
    "react": "^0.14.8",
    "react-dom": "^0.14.8",
    "webpack": "^1.13.1",
    "webpack-dev-server": "^1.14.1"
  },
  "devDependencies": {},
  "scripts": {
    "dev": "./node_modules/.bin/webpack-dev-server --content-base src --inline --hot",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "description": ""
}
`

webpack.config.js:

var debug = process.env.NODE_ENV !== "production";
var webpack = require('webpack');

module.exports = {
  context: __dirname + "/src",
  devtool: debug ? "inline-sourcemap" : null,
  entry: "./js/scripts.js",
  module: {
    loaders: [
      {
        test: /\.js?$/,
        exclude: /(node_modules|bower_components)/,
        loader: 'babel-loader',
        query: {
          presets: ['react', 'es2015', 'stage-0'],
          plugins: ['react-html-attrs', 'transform-class-properties', 'transform-decorators-legacy']
        }
      }
    ]
  },
  output: {
    path: __dirname + "/src/",
    filename: "scripts.min.js"
  },
  plugins: debug ? [] : [
    new webpack.optimize.DedupePlugin(),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false })
  ]
};

我的文件夹结构如下: enter image description here

我只把package.json和webpack.config.js放在这里,因为我怀疑其中只有一个是我手表无法工作的原因。

btw我遵循了这个教程(https://www.youtube.com/watch?v=MhkGQAoc7bc),甚至“我看了5次,我仍然无法找到问题,为什么这只手表不起作用。”

答案 0 :(得分:1)

你可能会遇到webpack对路径分隔符的敏感性,它已经多次咬过我。

诀窍是在指定上下文时使用=If([EWFMCodeSelect]="BREAK") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) ElseIf([EWFMCodeSelect]="DISC") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) ElseIf([EWFMCodeSelect]="MISS") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) ElseIf([EWFMCodeSelect]="NEUTR") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) ElseIf([EWFMCodeSelect]="NODISC") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) ElseIf([EWFMCodeSelect]="SHIFT") Then Sum([TimeDiff (ToInt)]ForEach([Clndr Date];[Time-Interval];[Agent Login];[Code])) path.sep而不是path.join。所以你要改变这个:

/

到此:

context: __dirname + '/src',
entry: './src/scripts.js',

请注意,该入口点仍然可以使用context: path.join(__dirname, 'src'), entry: './scripts.js', ,因为它已使用./解析,但require是webpack用于context的内容,你在上下文和条目中都有--watch,我认为这是多余的。
