Issues in installing forked package

[ahsan-ih]

I am having issues in installing the package from a forked url in a create-react-app.

Without the postinstall script
"postinstall": "cd node_modules/react-image-annotation && npm install && npm run build"
react is giving module not found error at import statement.

While with the postinstall script the installation throws error at "nwb build-react-component".
