Angular 15库项目angular.json中assets属性不被允许问题求助

问题出在你使用@angular-devkit/build-angular:ng-packagr构建类库时，在build.options里添加了assets配置——这个配置项是应用构建（browser builder）专属的，ng-packagr builder并不支持它，所以会抛出「属性不被允许」的错误。

修复步骤： #

1. 移除angular.json中的无效配置
   删掉build.options下的assets数组，修改后的build配置如下：

   "architect": {
     "build": {
       "builder": "@angular-devkit/build-angular:ng-packagr",
       "options": {
         "project": "projects/nad-frontend-modules/ng-package.json"
       },
       "configurations": {
         "production": {
           "tsConfig": "projects/nad-frontend-modules/tsconfig.lib.prod.json"
         },
         "development": {
           "tsConfig": "projects/nad-frontend-modules/tsconfig.lib.json"
         }
       },
       "defaultConfiguration": "production"
     },
     "test": {
       "builder": "@angular-devkit/build-angular:karma",
       "options": {
         "tsConfig": "projects/nad-frontend-modules/tsconfig.spec.json",
         "polyfills": [
           "zone.js",
           "zone.js/testing"
         ]
       }
     }
   }
   

2. 在ng-package.json中配置类库资源
   类库的静态资源需要在projects/nad-frontend-modules/ng-package.json里配置，添加assets字段指定要打包的资源路径：

   {
     "$schema": "../../node_modules/ng-packagr/ng-package.schema.json",
     "dest": "../../dist/nad-frontend-modules",
     "lib": {
       "entryFile": "src/public-api.ts"
     },
     "assets": [
       "src/assets",
       "src/styles"
     ]
   }
   

这样修改后，ng-packagr会正确识别并打包指定的静态资源，同时解决angular.json中的属性不允许错误。
