我正在使用webpack@2.2.0-rc.3并且extract-text-webpack-plugin@2.0.0-beta.4我有以下 webpack 配置:

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

module.exports = {
  entry: {
    app: './source/app.js',
    vendor: './source/vendor.js'
  },
  output: {
    path: path.resolve(__dirname, './.tmp/dist'),
    filename: '[name].[chunkhash].js'
  },
  module: {
    rules: [{
      test: /\.css/,
      use:[ ExtractTextPlugin.extract({
        loader: ["css-loader"],
      })],
    }],
  },
  plugins: [
    new ExtractTextPlugin({
      filename: "[name].[chunkhash].css",
      allChunks: true,
    })
  ]
};

vendor.js文件中,我有以下代码:

require("./asdf.css")

asdf.css我的代码中

body {
    background: yellow;
}

这是一个非常简单的设置,但是在运行 webpack 时出现此错误:

ERROR in ./source/asdf.css
Module build failed: ModuleParseError: Module parse failed: /home/vagrant/dorellang.github.io/source/asdf.css Unexpected token (1:5)
You may need an appropriate loader to handle this file type.
| body {
|     background: yellow;
| }

我究竟做错了什么?

尽管在 Webpack 2.2.0 中“use”应该替换(并且等同于)“loader”,但情况似乎并非如此。

看来您还不能将“使用”与 ExtractTextPlugin 一起使用。此外,您似乎不能将数组值用于“loader”(代替“use”)。

如果你替换这段代码:

use:[ ExtractTextPlugin.extract({
    loader: ["css-loader"],
})],

有了这个:

loader: ExtractTextPlugin.extract({
    loader: ["css-loader"],
}),

..它应该工作。(该替换适用于我类似的损坏测试用例。)

看起来主要的相关问题是https://github.com/webpack/extract-text-webpack-plugin/issues/265

您没有加载 css 文件,这就是您收到错误的原因。尝试将规则替换为您的webpack.congif.js这样:

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

module.exports = {
  ...  ...  ...
  module: {
    loaders: [
    {
      test: /\.js$/,
      loaders: ['babel'],
      include: path.join(__dirname, 'ur path here')
    },
    { 
      test: /\.css$/, 
      include: path.join(__dirname, 'ur path here'),
      loader: 'style-loader!css-loader'
    }
    ]
  }
};
