Javascript 网页包ZoneAwareError-预期为&x27；风格'；作为字符串数组（无预处理器）

我正在尝试正确配置网页包。我正在使用

目前，我在控制台中遇到一个异常，说

预期“样式”是一个字符串数组。

我更深入地研究了错误，发现在大多数情况下，这是由于webpack.config.js文件中缺少加载程序或配置不好造成的，但在我尝试创建它的嵌入式应用程序之前，该项目运行良好，在Shopify中。请记住，我目前没有使用任何预处理器

因此，我的问题是：

此错误是否由脚本在iFrame中运行引起的

我的配置是否有问题

这是我的webpack.config.js文件：

const webpack = require('webpack');
const merge = require('webpack-merge');
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;

module.exports = (env) => {

        context: __dirname,
        resolve: { extensions: ['.ts', '.js'] },

    };

    const clientBundleOutputDir = './wwwroot/dist';
    const clientBundleConfig = merge(sharedConfig, {
        entry: { 'bundle': './ClientApp/boot-client.ts' },
        output: { path: path.join(__dirname, clientBundleOutputDir) },
        plugins: [
            new webpack.DllReferencePlugin({
                context: __dirname,
                manifest: require('./wwwroot/dist/vendor-manifest.json')
            })

            })
        ] : [
                // Plugins that apply in production builds only
                new webpack.optimize.UglifyJsPlugin()
            ])
    });

    // Configuration for server-side (prerendering) bundle suitable for running in Node
    const serverBundleConfig = merge(sharedConfig, {
        resolve: { mainFields: ['main'] },
        entry: { 'main-server': './ClientApp/boot-server.ts' },
        plugins: [
            new webpack.DllReferencePlugin({

                sourceType: 'commonjs2',
                name: './vendor'


})
    ],
    output: {
        libraryTarget: 'commonjs',
        path: path.join(__dirname, './ClientApp/dist')
    },
    target: 'node',
    devtool: 'source-map'
});

return [clientBundleConfig, serverBundleConfig];

})

有人知道这是什么原因吗

我发现了问题。：）

这是复制粘贴错误。在我的两个组件中，初始化是：

@Component({ 
  selector: 'app', 
  template: require('./app.component.html'), 
  styles: require('./app.component.css') 
})

---

像这样。请注意，

styles

属性不是数组。显然，应该是这样。

使用require在component.ts文件中包含任何css。这将修复建议@Vignesh的问题。我知道这一点。我的组件初始化如下：

@component（{selector:'app'，template:require（'./app.component.html'），styles:[require（'./app.component.css'）]}）

我想这就是你的意思吧？当你在styleUrls中使用scss和css文件时，它会抛出错误请记住，我只使用普通的css文件。我不使用任何预处理器。你能详细解释一下你的意思吗？
