angular - Angular 6：多种配置（twas 环境）

问题描述

试图让 angular-cli 识别多个配置angular.json

C:\_dev\myapp>ng serve --configuration development
Configuration 'development' could not be found in project 'myapp'.
Error: Configuration 'development' could not be found in project 'myapp'.

片段是：

    "configurations": {
        "production": {
          "fileReplacements": [
            {
              "replace": "src/environments/environment.ts",
              "with": "src/environments/environment.production.ts"
            }
          ],
          "optimization": true,
          "outputHashing": "all",
          "sourceMap": false,
          "extractCss": true,
          "namedChunks": false,
          "aot": true,
          "extractLicenses": true,
          "vendorChunk": false,
          "buildOptimizer": true
        },
        "development": {
          "fileReplacements": [
            {
              "replace": "src/environments/environment.ts",
              "with": "src/environments/environment.development.ts"
            }
          ],
          "optimization": false,
          "outputHashing": "all",
          "sourceMap": true,
          "extractCss": true,
          "namedChunks": true,
          "aot": false,
          "extractLicenses": false,
          "vendorChunk": true,
          "buildOptimizer": false
        }
      }

src/environments/environment.development.ts确实存在

ng serve --configuration production

工作正常

解决方案

在angular.json文件的和部分中有一个configurations条目。服务部分也需要了解您的自定义配置。假设您的配置名称是debug，请将其添加到 serve 部分，如下所示buildserve

"projects": {
  "myApp": {
     [...]
     "architect": {
       "build": {
         [...]
         "configurations": {
           "production": { [...] },
           "debug": { [...] }
         }
       },
       "serve": {
         [...]
         "configurations": {
           "production": {
             "browserTarget": "myApp:build:production"
           },
           "debug": {
             "browserTarget": "myApp:build:debug"
           }
         }
       }
     }
   }
 }

不要忘记将myApp您的项目名称调整为等于angular.jsonproject中该部分的直接子项。两者都应该与您的配置相匹配。debugbuild

然后与

ng serve --configuration=debug
