角度6:多种配置(twas环境)

Question

试图让angular-cli识别出多个配置 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'.

该片段是:

    "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 

工作良好

Answer 1

angular.json文件的部分和configurations条目中有一个条目.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"
           }
         }
       }
     }
   }
 }

不要忘记调整myApp您的项目名称等于angular.json中该project部分的直接子项.两者都debug应该符合您在配置中的配置build.

然后服务

ng serve --configuration=debug
