Question

角度生产版本在我的项目中没有生成唯一的哈希。

以下是构建日志屏幕截图

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

请让我知道我在做什么错，或者提供任何解决方法。

我尝试过

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

即使在typescript或html中更改内容之后，仍然会为script.js产生相同的哈希值。

还有很多其他人也与您面临同样的问题。 Check Here。

如果官方的角度cli github上没有一个，我认为您不会找到解决问题的方法，但是根据答复，您可以尝试使用以下内容更新您的配置并让我知道如果可行？

      "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：预期文件会更改

您的实际代码仅在main.js中（我可以看到它得到了一个新的哈希）。其余文件很少更改。检查文件的含义here

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包含我们在的脚本部分中声明的脚本   angular.json文件

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

Answer 2

如果您使用的是 Angular 7+，则可以使用该命令

ng build --configuration prod --output-hashing all

确保在 angula.json 文件中设置了配置。

Angular-Prod Build不生成唯一的哈希
