我有一个本地环境和一个生产环境。在index.html中，我添加或删除脚本文件，具体取决于环境是本地环境还是生产环境。
我想要一个简单的方法来处理这个问题。在angular.json内部有一个file_replacement配置选项。这适用于将environment.ts切换为environment.prod.ts，但似乎无法将index.html文件替换为index.prod.html。

版本@angular/cli@6.1.0-beta.2支持此功能。
答案 1 :(得分：1)
我正在使用Angular 8，但我不知道为什么它对我不起作用。
但是我可以为任何构建配置指定index.html的位置（看起来也像serve）https://stackoverflow.com/a/57274333/3473303
答案 2 :(得分：1)
如in this github issue所述，更改angular.json以设置生产index.html：
"architect":{
"build": {
"options": {
"index": "src/index.html", //non-prod
},
"configurations": {
"production":{
"index": { //prod index replacement
"input": "src/index.prod.html",
"output": "index.html
}
}
}
}

在 Angular 8 中，“ fileReplacements”不适用于替换index.html。这是我的解决方法。
