问题描述
我在我的angular 8应用程序中本地运行了“ ng serve”，一切正常。但是，当我开始使用docker运行应用程序并且docker组成时，在@zxing/ngx-scanner上出现“无法在环境上下文中声明访问器”错误

有人知道原因吗？在修复应用程序之前，我无法对其进行测试。
在我的angular 8应用程序中启用PWA后，面对docker-compose构建中的问题。通常，当我执行“ ng serve”编译成功而没有任何错误时。
Package.json：
"@angular/animations": "^8.2.14","@angular/cdk": "^8.2.3","@angular/common": "^8.2.14","@angular/compiler": "^8.2.14","@angular/core": "^8.2.14","@angular/flex-layout": "^7.0.0-beta.23","@angular/forms": "^8.2.14","@angular/material": "^7.3.2","@angular/platform-browser": "^8.2.14","@angular/platform-browser-dynamic": "^8.2.14","@angular/router": "^8.2.14","@zxing/ngx-scanner": "3.0.0"
我找到了一些在tsconfig.json中添加skipLibCheck的解决方案，我不想跳过lib检查。
"angularCompilerOptions": {
"skipLibCheck": true
}
有人可以帮我解决这个问题吗？预先感谢。
解决方法
尝试启用PWA时，我错过了一些配置，因此能够找到问题并解决。还经过测试，问题不是由于@zxing/ngx-scanner
感谢所有花时间找到问题根源的人。
