您可能需要适当的加载程序来处理此文件类型babel和webpack

Question

因此，我的文件结构非常简单。

〜

/dist
/node_modules
/src
.babelrc
index.js
package.json
webpack.config.js

我要完成的工作是尝试运行“ webpack”命令，然后将其编译到dist文件夹中。 然后，我将module.export出来使用它。

但是，我一直遇到这个错误，该错误表明我可能需要这种文件类型的适当加载程序。 我觉得好像我需要开发所有我的开发包一样。

这是我的以下webpack.config.js以及package.json

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "webpack": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "babel-preset-stage-1": "^6.24.1",
    "lodash": "^4.17.4",
    "react": "^15.6.1",
    "react-dom": "^15.6.1"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "jsx-loader": "^0.13.2",
    "webpack": "^3.5.6",
    "webpack-dev-server": "^2.8.1"
  }
}


 module.exports = {
  entry: [
    './src/components/select.jsx'
  ],
  output: {
    path: __dirname + /dist/,
    publicPath: '/',
    filename: 'form-field.js'
  },
  module: {
    loaders: [{
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel-loader',
      query: {
        presets: ['react', 'es2015', 'stage-1']
      }
    }]
  },
  resolve: {
    extensions: ['.js', '.jsx']
  },
  devServer: {
    historyApiFallback: true,
    contentBase: './'
  }
};

您在加载程序中不允许使用任何文件类型。 添加一个test密钥。

  loaders: [{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    loader: 'babel',
    query: {
      presets: ['react', 'es2015', 'stage-1']
    }
  }]
