问题 I'm looking for a way to use ES6 Modules (import/export) syntax in my current RequireJS project. I can run my project directly in a recent browser, without build or Babel transformation. I build my project with r.js and Babel only for production. We would like to start building ES6 modules and use it with requireJS. Is there a way to do that ? NB : RequireJS does not load dependencies written in ES6. 回答1: Yes, RequireJS should be compatible with Babel's es2015-modules-umd plugin. So you

When I run the test of the component using Jest, I get the following error: ReferenceError: regeneratorRuntime is not defined I've determined through some reading that this is caused by babel-polyfill or regenerator-runtime not being applied correctly to Jest. However, I've tried installing both of those

问题 I have a React application (not using Create React App) built using TypeScript, Jest, Webpack, and Babel. When trying to run "yarn jest", I get the following error: I have tried removing all packages and re-adding them. It does not resolve this. I have looked at similar questions and documentation and am still misunderstanding something.
