Question

试图在生产模式下构建角度应用，但发现未知的目标和环境错误。

尝试以下方法：

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

我希望构建文件如main.js，vendor.js等。输出是：

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

Answer 1

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：

Answer 2

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

Answer 3

ng build --prod是生产环境的默认构建命令，无需其他参数，仅在需要实现某些特定条件时例如，如果您有其他环境，则可以运行

ng build --c= staging，其中c代表配置这是其他选择 https://angular.io/cli/build

Answer 4

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

确保在环境文件夹中创建一个environment.staging文件，并且还修改了angular.json文件以允许该命令。

"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"
        }
      }
    },

未知选项：“-target”，未知选项：“-environment”；尝试在产品中构建ng应用时
