Angular Uncaught TypeError:生成--prod后e不是构造函数(在ng serve上工作) [英] Angular Uncaught TypeError: e is not a constructor after build --prod (work on ng serve)
问题描述
在将我的角度应用程序上载到生产时，我遇到了问题. 该应用程序在开发中运行良好，并且在投入生产之前也可以正常工作.
I have a problem while uploading my angular application to production . The application works just fine in development and used to work before on production too.
要使用我的应用程序构建
To build my application I'm using:
ng build --prod --base-href="/site/"
该应用程序已构建，但带有以下警告:
The application is built, but with the following warnings:
WARNING in ./src/app/eco-header/eco-header.component.ngfactory.js 138:299-319 "export 'MAT_ICON_LOCATION' (imported as 'i9') was not found in '@angular/material/icon'

推荐答案
经过长时间的尝试，我发现在角度cli处存在一个打开的错误
after a long time of trying, I discovered that there is an open bug at angular cli
https://github.com/angular/angular-cli/issues/9929
ng build --prod --base-href ="/site/" -aot = false --build-optimizer = false
ng build --prod --base-href="/site/" --aot=false --build-optimizer=false
，目前暂时使用--aot=false --build-optimizer=false可以解决此问题.
and for now using --aot=false --build-optimizer=false temporarily solves the problem.
我会及时向官方发布有关角度团队将提供的信息和解决方案的信息.
Ill keep the post updated with official the information and solution that angular team will provide.
