jsx in index.js causing compiling error

I'm trying to use the library in a project created by `create-react-app`. There's a JSX at line 135.

Error in ./~/@mapbox/react-geocoder/index.js
Module parse failed: ob-ocm/node_modules/@mapbox/react-geocoder/index.js Unexpected token (135:16)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (135:16)

Start with index.js at line 135 and reproduce the create-react-app build failure shown in the report. Trace how that file is published and consumed, then verify the package no longer exposes syntax the reported build cannot parse. Done when the example project compiles without the Unexpected token at 135:16.
