Question

我用webpack创建了一个react应用程序，并试图将其部署到google app引擎。此应用程序没有服务器，一切都在浏览器中完成。我之前已经成功部署了简单的react应用程序，但是我认为webpack的切入点现在让我头疼。

我的应用程序已成功部署，但是导航到URL时，出现502错误的网关错误。当查看$gcloud app logs read时，我没有看到任何问题，我的应用已成功编译和构建，并且Google Cloud Console中的任何日志都无济于事。我尝试将所有devDependencies移至依赖项。

我的webpack配置：

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

module.exports = {
    entry: './src/index.js',
    mode: 'development',
    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel-loader',
                options: {
                    presets: [
                        '@babel/env'
                    ]
                }
            },
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    'css-loader'
                ]
            },
            {
                test: /\.(png|svg|otf)$/,
                loader: 'file-loader',
                options: {
                    name: '[path][name].[ext]'
                }
            }
        ]
    },
    resolve: {
        extensions: ['*', '.js', '.jsx']
    },
    output: {
        path: path.resolve(__dirname, 'dist/'),
        publicPath: '/dist/',
        filename: 'bundle.js'
    },
    devServer: {
        contentBase: path.join(__dirname, 'public/'),
        port: 8080,
        publicPath: 'http://localhost:8080/dist/',
        hot: true
    },
    devtool: "source-map",
    plugins: [new webpack.HotModuleReplacementPlugin()]
};

# [END app_yaml]

如果所有设置均正确，则可能的原因之一是scalability。如果不是扩展性问题，您是否有任何支持包/免费试用版？我建议您直接在support center中打开支持凭单，否则，您可以通过Google Issue Tracker与Google联系，因为5XX错误可能是由多种原因引起的，因此很难通过SO进行故障排除。< / p>
