我正在尝试为Angular 2项目创建一个生产版本。我从ng-build -prod命令中遇到这个错误..
从命令** ng build -prod 登录。**

通过 ng-serve 在本地部署应用程序可以正常工作。但是， ng build -prod 不会。任何帮助将非常感激。我认为我的角度包之间存在版本不匹配。
版本。

TypeError中的错误：无法读取未定义
的属性“匹配”
这不是代码中的错误。这是suppress-entry-chunks-webpack-plugin.js:40 filterFn

我跑了ng eject --prod之后就遇到了这个问题。从'styles'删除'entry'入口点会导致错误消失。谢天谢地，我还没有使用它。
不知道路线的原因。以下是该插件的来源：https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/plugins/suppress-entry-chunks-webpack-plugin.ts
答案 2 :(得分：-1)
删除package-lock.json文件并运行npm install。
npm install
