问题描述
我在 Angular 11 上创建了新项目 - 客户端。 然后将 ng 版本更新为 12 Angular。 然后安装通用： ng 添加@nguniversal/express-engine
然后我尝试运行我的 Universal Angular，但它抛出错误：
npm run dev:ssr
[email protected] dev:ssr ng 运行客户端：serve-ssr
这是一个简单的服务器，用于在本地测试或调试 Angular 应用程序。 它尚未经过安全问题审核。
请勿将其用于生产！
未在工作区中设置配置“开发”。 npm 错误！代码 1 npm 错误！路径 E:\PRACTICE\MYPETPROJECTS\tanechka\client npm 错误！命令失败 npm 错误！命令 C:\WINDOWS\system32\cmd.exe /d /s /c ng run client:serve-ssr
npm 错误！可以在以下位置找到此运行的完整日志： npm 错误！ C:\Users\1\AppData\Local\npm-cache_logs\2021-06-08T14_35_07_681Z-debug.log

}我尝试在服务的“配置”中添加“开发”：
但是没有用。
解决方法
我遇到了完全相同的问题，我第一次去环球影城。
我在 angular.json 的以下节点中添加了“开发”配置：-
projects->{project-name}->architect->build->configurations
projects->{project-name}->architect->server->configurations
由于我通常使用“生产”和“暂存”配置运行，我只是复制了暂存配置并进行了一些调整以停止文件替换，并在我习惯了服务器端渲染的同时为我提供了一个简单的调试平台。
,没有任何帮助。因此，我使用 Angular 12 删除了该项目，并使用 Angular 11 创建了一个新项目并添加了 Universal，运行 dev:ssr，它就可以工作了！
,我在 GitHub 上针对此主题创建了问题：https://github.com/angular/universal/issues/2158
工作决定是： 您可以尝试删除serve-ssr上的这一行：“defaultConfiguration”：“development”和“configuration.development path。然后在构建器下面添加如下选项： "options": { "browserTarget": "client:build","serverTarget": "client:server" },
Angular.json 必须有这样的视图（使用 Universal）
"serve-ssr": {
"builder": "@nguniversal/builders:ssr-dev-server","options": {
"browserTarget": "angular12-universal:build","serverTarget": "angular12-universal:server"
},"configurations": {
"production": {
"browserTarget": "angular12-universal:build:production","serverTarget": "angular12-universal:server:production"
}
}
},更改项目名称上的 angular12-universal
"serve-ssr": {
"builder": "@nguniversal/builders:ssr-dev-server","options": {
"browserTarget": "your-project-name-here:build","serverTarget": "your-project-name-here:server"
},"configurations": {
"production": {
"browserTarget": "your-project-name-here:build:production","serverTarget": "your-project-name-here:server:production"
}
}
},- 注意，在版本 12 中，还有一种新的 SSR 实验方式，要选择加入，您可以使用 ng add @nguniversal/common。
