ng build --prod failed

[Siddharth Kulat]

Hello Sir/ Ma'am,

I am using Syncfusion controls in my angular application. Currently I want to build my angular application, So I have triggered the below command on command prompt.

"ng build --prod"

But it is failing due to some Syncfusion angular controls. I am attaching some screenshots below for better understanding of problem.

I am using the below versions of Node, NPM, Angular

NPM Version: 6.13.4

Node Version: v12.16.1

Angular Version: 7.2.15.

Can you please check it and let me know asap ?

Thank You.

Hi Siddharth, 

Thanks for contacting Syncfusion Support. 

We have checked with your query and suspect that the reported issue (“ng build --prod produces build error”) may be caused due to lower version of angular devkit version is referred in your application. So, we suggest you update the angular dev kit version to V0.10.7 ("@angular-devkit/build-angular": "0.10.7"), since this version is compatible for angular 7 to get rid of the reported issue at your end. 

Please let us know if you need any assistance with this. 

Regards, 

Banupriya
