ng build --prod --configuration = production --base-href / folder_name / --aot无法使用Angular 6生成唯一的哈希

Question

ng build --prod --configuration=production --base-href 
         /folder_name/ --aot

命令始终会生成相同的哈希，而不是唯一的。我们正在使用Angular 6，并尝试创建用于产品部署的构建。以下是我的Angular和CLI版本：

Angular CLI: 6.2.5
Node: 10.12.0
OS: win32 x64
Angular: 6.1.10
... animations, common, compiler, compiler-cli, core, forms
... http, platform-browser, platform-browser-dynamic
... platform-server, router

Package                           Version

webpack                           4.19.1    

请让我知道我的配置出了什么问题。
