根据以下教程: https://angular-templates.io/tutorials/about/angular-internationalization-i18n-multi-language-app 和 https://medium.com/@ismaestro/angular-7-example-app-with-angularcli-angular-universal-i18n-official-firebase-66deac2dc31e，我正在尝试构建并使用一个使用i18n作为国际化系统的Angular 8应用程序。
然而，当我尝试运行

npm build:ssr (参见下文)时，我收到了 An unhandled exception occurred: Project target does not exist. 的错误信息。这里是 angular.json 文件的内容：

如我之前所述，我希望成功地运行我的Angular应用程序，并使用i18n。但是错误消息是：
[error] 错误：项目目标不存在。 在WorkspaceNodeModulesArchitectHost.getBuilderNameForTarget (/Users/user$ 在RunCommand.runSingleTarget (/Users/user/Desktop/Boilerplate/boilerpla$ 在RunCommand.runArchitectTarget (/Users/user/Desktop/Boilerplate/boiler$ 在RunCommand.run (/Users/user/Desktop/Boilerplate/boilerplate/node_modu$ 在RunCommand.validateAndRun (/Users/user/Desktop/Boilerplate/boilerplat$ 在process._tickCallback (internal/process/next_tick.js:43:7) 在Function.Module.runMain (internal/modules/cjs/loader.js:778:11) 在startup (internal/bootstrap/node.js:300:19) 在bootstrapNodeJSCore (internal/bootstrap/node.js:826:3)
如果有人已经遇到过相同的问题并能够解释我做错了什么？谢谢。
