我正在使用react和next js。我在next.config文件中添加了@ zeit / next-css和@ zeit / next-sass。

const withSass = require('@zeit/next-sass');
const withCSS = require('@zeit/next-css');

module.exports = withCSS(withSass());

现在我也想加载文件。我尝试执行此操作但不起作用并出现错误：

module.exports = withCSS(withSass({
    webpack (config,options) {
        config.module.rules.push({
            test: /\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$/,use: {
                loader: 'url-loader',options: {
                    limit: 100000
                }
            }
        });

        return config;
    }
}));
_app.js:7 Uncaught Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development.

我也安装了next-images，但是我不知道如何用css和sass对其进行配置？

const withSass = require('@zeit/next-sass');
const withCSS = require('@zeit/next-css');
const withImages = require('next-images');

module.exports = withCSS(withSass(withImages ()));//error and not working
