Getting this error code when I try to run the example in the readme:

./node_modules/react-github-btn/index.js
Module parse failed: Unexpected token (10:83)

import GitHubButton from "react-github-btn";

Update: the module seems to work fine on a newly-created React app.

It's still not working on my project tho, even after updating react and react-dom to ^17.0.1. Same error.

The issue is likely that you have old version of react-scripts.

You need at least react-scripts>=2.0.3, ideally upgrade it to latest version if possible.

Here is the critical commit that makes the difference if you're interested: https://github.com/facebook/create-react-app/commit/3d4440812c62e692019f72503a60c6240df2f805

I'll take your word for it re: react-scripts... my app is having trouble updating to the latest version. I ended up not using the module anyway, as I needed the buttons to be larger than the largest size offered. So i made my own components. But thanks for the prompt response anyway! cheers.
