在我的角度应用程序中使用外部角度元素(webcomponents)时出现以下错误。
未捕获(承诺):TypeError:无法读取未定义的属性“调用” TypeError:无法读取未定义的属性“调用”
它仅在以生产模式构建(ng build --prod)、优化设置为 true 且延迟加载时发生。
package.json 依赖:
"devDependencies": {
"@angular-devkit/build-angular": "^0.7.0-rc.0",
"@angular/cli": "^6.2.3",
"@angular/compiler-cli": "^6.1.8",
"@angular/language-service": "^6.0.3",
"@types/jasmine": "~2.8.6",
"@types/jasminewd2": "~2.0.3",
"@types/node": "~8.9.4",

"karma": "~1.7.1",
"karma-chrome-launcher": "~2.2.0",
"karma-coverage-istanbul-reporter": "~2.0.0",
"karma-jasmine": "~1.1.1",
"karma-jasmine-html-reporter": "^0.2.2",

"protractor": "~5.3.0",
"ts-node": "~5.0.1",
"tslint": "~5.9.1",
"typescript": "~2.7.2"
}
以下是复制步骤。
应用程序源(GIT 存储库):
https://github.com/gowthamr123/repro-app
运行 npm install do ng serve 并转到以下 url 后:
http://localhost:4200/selfcare/tariff-change
它会正常工作。
现在在生产模式下运行 ng serve --prod
发生错误:
未捕获(承诺):TypeError:无法读取未定义的属性“调用” TypeError:无法读取未定义的属性“调用”
任何帮助将非常感激。
