当我使用Webpack2编译文件时。它显示以下警告:



我检查了github页面,但没有找到如何解决此问题的方法。这是我的配置:

// webpack 2 configuration
// https://webpack.js.org/guides/migrating/

const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    watch: true,
  inline: true,
  resolve: {
    modules: [
      'node_modules',
      path.resolve(__dirname, './app'),
    ],
    //http://webpack.github.io/docs/configuration.html#resolve-alias
    alias: {
      lib: path.resolve('./lib'),
      res: path.resolve('./res'),
      style: path.resolve('./style'),
      //make sure it can be load by 'jquery'
      jquery$: 'jquery',

        loader: ExtractTextPlugin.extract({

    ]
  },
  plugins: [

    }),

    new ExtractTextPlugin({filename: '[name].css'}),
    new webpack.LoaderOptionsPlugin({
      debug: true,
      // test: /\.xxx$/, // may apply this only for some modules
      options: {
        // for @import path in the style file
        sassLoader: {includePaths: [path.resolve('./style') + '/']}
      }
    }),
  ]
};

任何想法将不胜感激。

最佳答案

加载程序使用loaderUtils.parseQuery()来获取传递给加载程序的选项。它已被替换为 loaderUtils.getOptions() 。您可能正在使用仍然使用parseQuery的加载器。您在webpack配置中使用的所有加载程序应已更改为使用getOptions,但您可能正在使用旧版本的加载程序,但未包含此更改。要解决此问题,您只需将装载机升级到最新版本即可。

如果出于某种原因您不想升级所有加载程序,则可以在webpack配置文件中添加以下行(不是一个选项):

process.traceDeprecation = true;

这将为您提供堆栈跟踪,其中使用了parseQuery,因此您可以标识实际使用它的加载器并升级该特定加载器。

事实证明,最新的babel-loader仍在使用parseQuery,它将在下一个主要版本中进行更改,并且已在v7.0.0-alpha中提供。但是,如果您不想使用Alpha版本,则必须忍受警告,直到v7.0.0出现。
