尝试在 prod 模式下构建 Angular 应用程序，但发现未知目标和环境错误。

尝试以下：

ng build --target=production --base-href /
ng build --target=production --environment=prod
ng build --prod --env=prod

我期望构建文件，如 main.js、vendor.js 等。输出是：

Unknown option: '--target'
Unknown option: '--environment'

ng build --configuration=staging
ng server --configuration=staging

确保您在环境文件夹中创建一个environment.staging文件，并修改该angular.json文件以允许此命令。

"build": {
"production": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.prod.ts"
                }
              ]
            },
            "staging": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.staging.ts"
                }
              ]
            }
}
    

"serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "letsfarm-frontend:build"
      },
      "configurations": {
        "production": {
          "browserTarget": "letsfarm-frontend:build:production"
        },
        "staging": {
          "browserTarget": "letsfarm-frontend:build:staging"
        }
      }
    },

ng build --prod 是生产环境的默认构建命令，不需要其他参数，只要有特定的你需要实现例如如果你有另一个环境你可以运行

ng build --c= staging其中 c 代表配置这里是更多选项 https://angular.io/cli/build

您可以使用此构建命令 ng build --base-href="/" --env=prod

发现以下命令在没有任何参数的情况下执行良好：

ng build --prod

输出：
