如果我在没有 --prod 选项（o 完整字符串 --prod --aot --build-optimizer --common-chunk --vendor-chunk --named-chunks --source-map --verbose=true）的情况下构建，构建是正确的，但我有这个结果：
✔ Browser application bundle generation complete.
✔ ES5 bundle generation complete.
✔ Copying assets complete.
✔ Index html generation complete.

如您所见，我有非常大的文件 vendor-es5.js 13.42 MB 和 vendor-es2015.js 11.39 MB
如果我运行生产脚本 ng build --prod --aot --build-optimizer --common-chunk --vendor-chunk --named-chunks --source-map --verbose=true，我会收到此错误：

谁能告诉我如何解决这个问题？我不明白为什么我会收到这个错误
谢谢 安杰洛
更新
我弄清楚出了什么问题并导致了生产构建错误。
在我的 angular.json 中我犯了一个错误...在脚本元素中我放了一个 .css ("node_modules/primeng/resources/themes/saga-blue/theme.css")
通过删除它，生产构建是可以的，生产大小约为 4MB...巨大但并不巨大
