Angular 4，意外标记：ng构建期间的名称（主题）——prod

我有一个角度4应用程序

我可以使用

ng build

但是，当我运行

ngbuild--prod

时，会抛出以下错误

UglifyJs中的vendor.4008cf7dff2b98412878.bundle.js错误 意外标记：名称（主题） [供应商4008cf7dff2b98412878.bundle.js:19471,6]

当我做一些研究时，我发现uglifyjs不能与es6一起工作，我在Tconfig文件中将目标更改为es5

但我一直在犯这个错误

我不明白怎么了

这是我的cli版本

这是我的tsconfig.json文件

我解决了这个问题

我用了这个“”包。我从我的应用程序中取出了未安装的软件包，问题就解决了

现在，我可以使用

ngbuild--prod

命令成功地构建项目。
