How are you using Babel?

Input code

Using esbuild and @testing-library/dom I run into this error :

Uncaught SyntaxError: The requested module '/node_modules/@babel/runtime/regenerator/index.js?v=8bc5bdce' does not provide an export named 'default'

Because @testing-library/dom uses `import _regeneratorRuntime from '/node_modules/@babel/runtime/regenerator/index.js';

Sadly this file https://github.com/babel/babel/blob/main/packages/babel-runtime/regenerator/index.js lacks of the default export.

Configuration file name

Configuration

Current and expected behavior

https://github.com/babel/babel/blob/main/packages/babel-runtime/regenerator/index.js should have the default export.

Environment

@babel/runtime@7.14.6

System: OS: macOS 11.4 Binaries: Node: 14.16.1 - ~/.nvm/versions/node/v14.16.1/bin/node Yarn: 2.4.1 - /usr/local/bin/yarn npm: 6.14.12 - ~/.nvm/versions/node/v14.16.1/bin/npm npmPackages: @babel/core: ^7.14.6 => 7.14.6 @babel/eslint-parser: ^7.14.5 => 7.14.5 babel-loader: ^8.2.2 => 8.2.2 eslint: ^7.5.0 => 7.28.0 jest: ^27.0.4 => 27.0.4

Possible solution

Add the default export

regenerator-runtime only provides a CJS entry point. You need to configure your bundler to support CJS files, or you cannot transform generators to ES5.

I'm also using esbuild and @testing-library/react and am getting this error

[nicolo-ribaudo]

You need to configure esbuild to be able to import commonjs files.

Would like to ask how the final solution?

This is an esbuild configuration problem; it's unlikely that someone in this repository can help 😅
