Hi Abraham! I am facing the exact same error in a different context (trying to build a portlet to publish my Angular app via Liferay).

Were you able to resolve this problem?

I would be grateful if you could please let me know (by responding to this comment).

Thank you!

Error: EMFILE: too many open files, while deploying react widget.

I've created a React application and done all necessary steps to makes the app available as a widget for using on site pages in Liferay. But when I run the command " npm run deploy" I'm getting the following error in cmd :

> my-react-app@1.0.0 deploy C:\Users\.......\React Applications\my-react-app
> npm run build && lnbs-deploy

> my-react-app@1.0.0 build C:\Users\.......\React Applications\my-react-app
> babel --source-maps -d build src && npm run copy-assets && liferay-npm-bundler

Successfully compiled 19 files with Babel (4981ms).

> my-react-app@1.0.0 copy-assets C:\Users\.......\React Applications\my-react-app
> lnbs-copy-assets

Project assets copied.
