Angular - Prod Build 不生成唯一的哈希值

Question

Angular 生产构建不会在我的项目中生成唯一的哈希值。

以下是构建日志截图

无法在新的 angular cli 项目中重现此问题，似乎我的项目中存在一些问题。

我正在使用角度 - 6.0.3

下面是angular.json

请让我知道我做错了什么，或者提供任何解决方法。

编辑：

我试过了

ng build --aot --output-hashing=all
ng build --output-hashing=all

即使在更改 typescript 或 html 中的内容之后，这仍然会为 script.js 产生相同的散列。

有很多其他人和你面临同样的问题。检查这里。

如果官方 angular cli github 上没有解决方案，我认为您不会找到解决问题的方法，但是根据回复，您能否尝试使用以下内容更新您的配置，并让我知道它是否有效?

      "configurations": {
        "production": {
          "fileReplacements": [
            {
              "replace": "src/environments/environment.ts",
              "with": "src/environments/environment.prod.ts"
            }
          ],
          "optimization": true,
          "outputHashing": "all",
          "sourceMap": false,
          "extractCss": true,
          "namedChunks": false,
          "aot": true,
          "extractLicenses": true,
          "vendorChunk": false,
          "buildOptimizer": true
        }
      }

编辑：需要更改的文件

您的实际代码仅在 main.js 中（我可以看到它获得了新的哈希值）。其余文件很少更改。在此处检查文件的含义

main.js 包含我们所有的代码，包括组件（ts、html 和 css 代码）、管道、指令、服务和所有其他导入的模块（包括第三方）。

scripts.js 包含我们在 angular.json 文件的 scripts 部分声明的脚本

"scripts": [
   "myScript.js",
]
