configuration.module有一个未知的属性'loaders'

Question

我输出的错误:

配置对象无效.Webpack已使用与API架构不匹配的配置对象进行初始化. - configuration.module有一个未知的属性'loaders'.这些属性是有效的:object {exprContextCritical？,exprContextRecursive？,exprContextRegExp？,exprContextRequest？,noParse ?, rules？,defaultRules？,unknownContextCritical？,unknownContextRecursive？,unknownContextRegExp？,unknownContextRequest？,unsafeCache？,wrappedContextCritical？,wrappedContextRecursive？,wrappedContextRegExp ？,strictExportPresence？,strictThisContextOnImports？} - >影响正常模块的选项(NormalModuleFactory).

我的webpack.config.js:

var webpack = require('webpack');
var path = require('path');

var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');

var config = {
  entry: APP_DIR + '/index.jsx',
  module : {
    loaders : [
      {
        test : /\.jsx?/,
        include : APP_DIR,
        loader : 'babel-loader'
      }
    ]
  },
  output: {
    path: BUILD_DIR,
    filename: 'bundle.js'
  }

};


module.exports = config;

我的webpack版本:

webpack@4.1.1

Answer 1

您应该在webpack 4中更改loaders为rules:

更改:

loaders 

至:

rules

来源:https://webpack.js.org/concepts/loaders/#example

例:

module.exports = {
  module: {
    rules: [
      { test: /\.css$/, use: 'css-loader' },
      { test: /\.ts$/, use: 'ts-loader' }
    ]
  }
};

Answer 2

rules在webpack 4中使用而不是loaders.
