无法使用Angular 7创建生产版本

Question

我使用Angular 6开发了一个运行良好的应用程序。

我升级到Angular7。整个应用程序被破坏。 恢复该应用程序花了4天。 现在，我可以在开发模式下构建应用程序，并且可以正常工作。

我正在尝试进行生产。 但是，出现以下错误。

请帮助，以便我可以创建生产版本。

问候，帕萨

命令：ng build --prod --aot

输出：

angular.json文件已损坏。 代替

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

我有以下内容：

"fileReplacements": [
                {
                  "replace": "src/undefined",
                  "with": "src/environments/environment.ts"
                }
              ]
