webpack 打包css url问题

Question

各位好！
我使用vue-cli生成的工程，将fontawesome整个放在工程中一起打包，但是css文件build之后，里面的url引用会发生变化，导致@font-face{font-family:'FontAwesome';src:url('fontawesome-webfont.eot?v=4.7.0')引用不到实际的文件而报错。
我的环境如下，目录结构

    // In our experience, they generally work as expected,
    // just be aware of this issue when enabling this option.
    cssSourceMap: false
  }
}

请问各位，我需要修改什么配置，才能确保编译后的css里url引用是正确的？

这个问题我们之前遇到过，应该是webpack loader的问题。

{
    test: /\.(woff2?|eot|ttf|otf|svg)(\?.*)?$/,
    loader: 'url-loader',
    options: {
       limit: 10000,
       name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
   }
}

可以试试取消limit

test: /.(woff2?|eot|ttf|otf|svg)(?.*)?$/,
还有你的字体文件中有.woff后缀的文件，但是正则匹配的时候却没有匹配到，你也可以把woff结尾的这个文件删除掉。

最好能把报错信息贴出来，可以更好的定位错误。
