ReferenceError：未定义resolve（`ExtractTextPlugin.extract`）

Question

在问这个问题之前我搜索了SO，得到了相关文章： ReferenceError: resolve is not defined

但它不适合我的情况，因为我的webpack配置错误，我不知道为什么会遇到这个问题。

当我使用npm run build时，我收到了以下错误：

/Users/ldsole/Desktop/my-project/web/wx_backup/webpack.base.config.js:51
                use: ExtractTextPlugin.extract({
                                       ^

你看到了npm ERR! This is probably not a problem with npm. There is likely additional logging output above.，我不知道为什么会出错。

我的原因错误代码（webpack.base.config.js）如下：

  {
    test: /\.css$/,
    use: ExtractTextPlugin.extract({   // there is the error line.
      use: ['css-loader?minimize', 'autoprefixer-loader'],
      fallback: 'style-loader'
    })
  },
