部署后源文件 (.ts) 未显示在开发工具中

Question

我只能在本地看到 .ts 源文件，但部署后，我在任何环境中都看不到它们。我已经将我的源映射设置为true，并且还在服务下设置了我的browserTarget。它仍然不起作用。请帮忙！

这是我的 angular.json 文件

}

这是我的 package.json 的片段

"name": "UI-App",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "jest",
    "lint": "ng lint",
    "lint:fix": "ng lint --fix",
    "format": "prettier --write src",
    "format:check": "prettier --check src",
    "e2e": "ng e2e",
    "clean": "node scripts/clean.mjs"
  },

这是我本地的开发工具。我可以看到 src 文件夹。 这是我部署应用程序后的开发工具。看不到 src 文件夹。

源映射文件允许开发工具将 JS 文件“转换”回 TS。

确实不可读。

如果你希望在构建时获得与本地环境相同的结果，那么你应该运行

npx ng serve -c development 

这将使用开发环境，该环境被配置为将源文件保留在您的配置中。

需要注意的是，建议不要在生产版本中这样做。
