无法进行 ng build 优化，出现 Angular 错误

我正在使用Angular 13构建实时聊天应用，我尝试构建我的Angular应用程序，以便在我的Node.js web服务器上进行测试，但每次尝试时：

ng build

我在控制台中得到以下错误：enter image description here

我确实尝试删除错误消息显示的文件，但总是出现新文件，我认为这可能是生产环境的错误配置，但是它是默认配置，所以我不知道发生了什么 ://

I hope someone can help me to understand why this happen, thanks, have a nice day.

这个问题可能类似...用户有一个 angular.json 配置的示例，可以防止优化错误，可能会有所帮助 https://dev59.com/kFEG5IYBdhLWcg3wMGPV - undefined

我遇到了类似的问题， 错误：优化错误 [main.64ac3ee7acfe838b.js]：错误：服务已停止 我在使用命令“bg build --output-path docs --base-href /”运行 Angular 构建时遇到了上述错误。

在添加上述解决方案后，问题最终得到解决。

注意：将配置添加到 architect 部分，而不是 serve 部分 ....... "architect": { "build": { "builder": "@angular-devkit/build-angular:browser", "options": { "outputPath": "dist/my-portfolio", "index": "src/index.html", "main": "src/main.ts", "polyfills": [ "zone.js" ], "tsConfig": "tsconfig.app.json", "assets": [ "src/favicon.ico", "src/assets" ], "styles": [ "src/styles.css" ], "scripts": [] }, "configurations": { "production": { "optimization": false, "budgets": [ { "type": "initial", "maximumWarning": "2mb", "maximumError": "5mb" }, .......

在angular.json的生产环境中添加这段代码。

...
"configurations": {
   "production": {
      "optimization": false,
...
}
...

"configurations": { "production": { "optimization": false, .... } ...“配置”：{“生产”：{“优化”：false，....} ... - undefined
请使用代码格式来编写代码 - undefined

对于大多数人来说，在生产中关闭优化并不是一个可行的答案。 - undefined
