脚本错误。 xxxjs 来自 Terser 构建 angular 构建 angular 项目以部署到 heroku

Question

我想将我的代码部署到 heroku，但在构建我的 angular 应用程序时总是遇到错误。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 click to view the error

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

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

它指出了整个应用程序中有句法的地方。一旦解决，我的构建就成功了
