Fixing "ReferenceError: babelHelpers is not defined" in react-accessible-accordion@2.3.1

I’ve run into this exact issue with older versions of this package before—here’s what’s going on and how to fix it:

The react-accessible-accordion@2.3.1 UMD build was compiled with Babel but didn’t inline the required babelHelpers into its code, instead expecting them to be available globally in your runtime. Reinstalling dependencies won’t fix this because you’re just pulling down the same problematic build each time.

Try these solutions in order:

1. Use Babel’s transform-runtime plugin to inject helpers

This is the most reliable long-term fix, as it ensures your project provides the necessary babelHelpers without global pollution:

First install the required packages:

npm install @babel/plugin-transform-runtime --save-dev
npm install @babel/runtime --save

Update your Babel config (either babel.config.js or .babelrc) to include the plugin:

{
  "plugins": [
    ["@babel/plugin-transform-runtime", {
      "helpers": true,
      "regenerator": true,
      "useESModules": false
    }]
  ]
}

Rebuild your project, and the error should disappear.

2. Upgrade to a newer version of the package

The maintainers fixed this compilation issue in later releases. Upgrading to the latest stable version will eliminate the problem entirely:

npm install react-accessible-accordion@latest

This is the simplest fix if you don’t have strict version constraints on the package.

3. (Temporary workaround) Manually import babelHelpers

If you can’t modify your Babel config or upgrade the package, you can manually inject the helpers globally:

Install the babel-helpers package:
```
npm install babel-helpers --save
```
Add this line to the very top of your project’s entry file (like src/index.js):
```
import 'babel-helpers';
```
