我正在尝试使用Jenkins设置构建管道。我的构建似乎可以正常工作，但是当我尝试加载从构建生成的文件时，我在浏览器控制台中看到此错误。
Object doesn't support property or method 'getMetadata'
在我的项目代码中的任何地方都没有调用Reflect.getMetadata()，但我意识到其中一个依赖项可能会沿线运行。在Webpack创建的生成的main.js文件中，错误发生在Reflect.getMetadata()调用处。页面上没有任何内容。它灾难性地失败了，只是空白。
我找到了人们遇到类似问题的参考，但是我尝试了他们的解决方案，但仍然遇到相同的运行时错误。
我尝试了“ bashleigh”和“ schtauffen”所说的对他们有用的方法：https://github.com/rbuckton/reflect-metadata/issues/44
但是当我从reflect-metadata安装npm库时，它确实告诉我它已被弃用，不需要包含。
npm i --save @types/reflect-metadata
npm WARN deprecated @types/[email protected]: This is a stub types definition for reflect-metadata (https://github.com/rbuckton/ReflectDecorators). reflect-metadata provides its own type definitions, so you don't need @types/reflect-metadata installed!
[无论如何，我都尝试运行包含该版本的构建，只是为了查看会发生什么，但是没有任何变化。同样的错误。
这是我的package.json：
