如何以Angular 改变环境

在我的项目中，我有3个环境文件(dev、staging、production).我想 for each dist文件夹更改它们(当部署到dev时，我需要envi-dev链接从中获取数据.对于staging和prod也是如此)

export const environment = {
  production: true,
  hmr: false,
  backend: false,
  staging: false,
  apiKey: 'prodKey',
  API_URL: "my backend link"
};

当然，在dev和staging env中生产是错误的..

"configurations": {
            "production": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.prod.ts"
                }
              ],
              "optimization": true,
              "outputHashing": "all",
              "sourceMap": false,
              "namedChunks": false,
              "extractLicenses": true,
              "vendorChunk": false,
              "buildOptimizer": true,
              "budgets": [
                {
                  "type": "initial",
                  "maximumWarning": "2mb",
                  "maximumError": "5mb"
                },
                {
                  "type": "anyComponentStyle",
                  "maximumWarning": "6kb",
                  "maximumError": "10kb"
                }
              ],
              "outputPath": "dist/production"
            },

但是当我构建时，我通常会输入一个文件，并使用另一个文件来构建和部署，就像我的api文件中一样

import { environment } from 'src/environments/environment';

// import { environment } from "src//environments/environment.stage";
// import { environment } from "src//environments/environment.prod";

const API_URL = environment.API_URL;

命令是:ng build和ng build--配置=暂存和ng build--prod

但是我不想继续 comments API envir.如上所述，我希望在 for each 环境构建和更改dist文件后，它会自动更改，这样我就可以正常部署到git并执行正常的管道.

知道吗？谢谢
