node.js - npm 错误!缺少脚本 : build:universal

Question

我正在尝试在服务器端运行我的 Angular 应用程序，但我遇到了以下错误:

npm ERR! missing script: build:universal

npm ERR! A complete log of this run can be found in: npm ERR!
/home/training/.npm/_logs/2018-10-03T11_50_40_593Z-debug.log

我使用官方的 Angular 应用程序来做这件事

https://angular.io/guide/universal

通用构建导致如下所示的错误:

正如我在评论中暗示的那样，您可能忘记将构建脚本添加到您的项目中:

来自 universal docs

Build and run with universal: Now that you've created the TypeScript and Webpack config files and configured the Angular CLI, you can build and run the Universal application.

First add the build and serve commands to the scripts section of the package.json:

"scripts": {
    ...
    "build:ssr": "npm run build:client-and-server-bundles && npm run webpack:server",
    "serve:ssr": "node dist/server",
    "build:client-and-server-bundles": "ng build --prod && ng run angular.io-example:server",
     "webpack:server": "webpack --config webpack.server.config.js --progress --colors"
    ...
}

所以检查你 package.json 并再次尝试构建..
