Webpack失败了,巴贝尔已经转移到了babel-core

Question

我已经按照不同开发人员发布的stackoverflow帖子的解决方案.但是,他们都没有帮助解决我遇到的问题.我做的事情很少

1. 卸载babel
2. 安装babel-core,babel-cli
3. 升级到节点v6.2.2
4. 重新安装webpack
5. 炸毁node_modules并再次运行npm install

所有上述内容从未修复此错误

webpack: bundle is now VALID.

这是我的package.json

{
  "name": "react-es6-setup",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.2.0",
    "react-dom": "^15.2.0"
  },
  "devDependencies": {
    "babel-core": "^6.10.4",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1"
  }
}

和webpack.config.js

module.exports = {
  entry: './main.js',
  output: {
    path: './',
    filename: 'index.js'
  },
  devServer: {
    inline: true,
    port: 3333
  },
  module: {
    loaders: [
        {
          test: /\.js$/,
          exclude: 'node_modules',
          loader: 'babel',
          query: {
            presets: [ 'es2015', 'react' ]
          }
        }
    ]
  }
}

和node_modules的目录列表

$ ls -l node_modules/ |grep react
drwxr-xr-x    6 admim  207825898    204 Jul  6 02:02 babel-helper-builder-react-jsx/

Answer 1

其loaders: 'babel-loader'在webpack.config.js固定的我-的问题

使用npm安装这些依赖项

"babel-core": "^6.1.2",
"babel-loader": "^6.1.0",
"babel-plugin-transform-runtime": "^6.1.2",
"babel-preset-es2015": "^6.1.2",
"babel-preset-stage-0": "^6.1.2",
"babel-runtime": "^5.8.0",

在webpack.config.js文件中,有这个代码:

const path = require('path');
module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'dist.js',
    publicPath: "js"
  },
  module: {
    loaders: [
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      }
    ]
  }
}

Answer 2

尝试这个：

先删除node_module文件夹，然后

npm init
npm i webpack -S (Install Globally too)
npm i babel-loader babel-preset-es2015 babel-preset-react babel-core -S
npm i react react-dom -S`

确保您的 webpack.config.js 具有：

loaders: [
    {
      test: /\.js$/,
      exclude: 'node_modules',
      loader : 'babel-loader',

...

然后run webpack -d
