Hi, I am trying to install the openvidu-call on AWS Ubuntu 18.04 LTS. Installed the backend and started it without any issues ubuntu@ip-172-31-32-123:~/openvidu-call/openvidu-call-back$ sudo npm run start But when i try to serve the front-endusing the below command, the compilation hangs while compiling @angular/core. Please find the output below. cd openvidu-call-front sudo npx ng serve --open To disable this warning use “ng config -g cli.warnings.versionMismatch false”. Warning: Entry point ‘ngx-linkifyjs’ contains deep imports into ‘/home/ubuntu/openvidu-call/openvidu-call-front/node\_modules/linkifyjs/plugins/hashtag’, ‘/home/ubuntu/openvidu-call/openvidu-call-front/node\_modules/linkifyjs/plugins/mention’, ‘/home/ubuntu/openvidu-call/openvidu-call-front/node\_modules/linkifyjs/string’. This is probably not a problem, but may cause the compilation of entry points to be out of order. Compiling @angular/core : module as esm5 Can someone please help me out as to where I am going wrong. Regards, Sudhir KP ---

Hi, I would like get the answer to the following questions: 1. What do you mean with “_the compilation hangs while compiling @angular/core_”? 2. Why are you using **ng serve** in a AWS Instance? 3. Why are you starting openvidu-call on development mode? 4. Have you followed and read the [openvidu-call guide](https://docs.openvidu.io/en/2.14.0/demos/openvidu-call/)? ---

You have to packge the application “openvidu-mvc-node” and then deploy it in the server. I recommend you to use Docker. Regards
