Unable to install on CentOS 7

[ccpplinux]

I am trying to install this package on my CentOS VPS. After running npm install command, following warning messages were displayed:

npm WARN ws@7.3.1 requires a peer of bufferutil@^4.0.1 but none was installed.
npm WARN ws@7.3.1 requires a peer of utf-8-validate@^5.0.2 but none was installed.
npm WARN video-chat2@1.0.0 No repository field.
npm WARN video-chat2@1.0.0 license should be a valid SPDX license expression 

And after running npm start command, following error messages were displayed:

> video-chat2@1.0.0 start /home/ccpplinux/decentralized-video-chat
> node server.js
