Question

问题是，当使用普通ReactJS （没有React DnD）时，Babel和Webpack编译我的.js文件完美无缺，但在尝试使用时在我的项目中反应DnD ，使用Webpack和Babel编译js时出现错误：

ERROR in ./~/disposables/modules/index.js
Module build failed: ReferenceError: [BABEL] D:\MyProject\React_002\node_modules\disposables\modules\index.js: Using removed Babel 5 option: D:\MyProject\React_002\node_modules\disposables\.babelrc.stage - Check out the corresponding stage-x presets http://babeljs.io/docs/plugins/#presets

 @ ./~/react-dnd/lib/DragSource.js
 @ ./~/react-dnd/lib/index.js
 @ ./src/js/Container.js
 @ ./src/js/script.js

这是我的 webpack.config.js 文件

var path = require('path');

module.exports = {
  entry: './src/js/script.js',
  output: {
    path: path.join(__dirname, 'dist/js'),
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.jsx?$/,
        loader: 'babel-loader',
        exclude: '/node_modules/'
      }
    ]
  }
};

这是我的 .babelrc 文件

{
  "presets" : ["es2015", "react"]
}

这是我的 package.json 文件

{
  "name": "React_002",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "babel": "babel",
    "webpack": "webpack",
    "build": "rimraf dist && webpack --watch",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.5.4",
    "react-dnd": "^2.3.0",
    "react-dnd-html5-backend": "^2.3.0",
    "react-dom": "^15.5.4"
  },
  "devDependencies": {
    "babel-core": "^6.24.1",
    "babel-loader": "^7.0.0",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "rimraf": "^2.6.1",
    "webpack": "^2.4.1"
  }
}

如何解决这个问题？和这个问题的原因？感谢

您实际上并未从规则中排除node_modules。您传入了一个与绝对路径/node_modules/对应的字符串，即node_modules中的/目录，即文件系统的根目录。它应该是正则表达式，而/regex/是正则表达式文字语法，但是如果你在它周围添加引号，它就会变成一个字符串（类似于在数组文字周围加上引号会发生的情况）。另请参阅MDN - Regular Expressions。

你的规则应该是：

{
  test: /\.jsx?$/,
  loader: 'babel-loader',
  exclude: /node_modules/
}

在React DnD项目上使用Babel和Webpack时出现此错误
