我希望将我的代码部署到 heroku，但是在构建我的 Angular 应用程序时我总是遇到错误。我尝试使用以下命令来构建我的 Angular 项目。'ng build --prod','ng build --aot --prod' 这两个命令都导致相同的错误。ng build --aot --prod 点击查看错误

附上我的 package.json，为 package-lock.json 添加了屏幕截图。packagelock.json 包锁

当我使用以下命令构建 Angular 应用程序时，问题已解决

build --prod --named-chunks --verbose --build-optimizer=false --source-map

它指出了应用程序中存在语法的地方。解决后我的构建成功
