In Babel 7 you need to install two packages are:
npm install --save @babel/runtime npm install --save-dev @babel/plugin-transform-runtimeAnd add more .babelrc like this:
{ "presets": ["@babel/preset-env"], "plugins": [ ["@babel/plugin-transform-runtime", { "regenerator": true }] ] }Hope it is helpful for you.

1. You need to install
regenerator-runtimenpm install --save regenerator-runtime2. Update your webpack file
entry: ["regenerator-runtime/runtime.js", "<your enter js file>"]For example:
module.exports = { entry: ['regenerator-runtime/runtime.js', './test.js'] };3. Import
import 'regenerator-runtime/runtime'at the top of the file, you got an error. - t0

I got the same error and I changed my .babelrc file as below:
module.exports = { presets: [ [ '@babel/preset-env', { targets: { esmodules: true, }, }, ], ], }And it worked for me.
