Uncaught ReferenceError: regeneratorRuntime is not defined

Problem Description:

When compiling es6 with babel, I encountered the error Uncaught ReferenceError: regeneratorRuntime is not defined

cause:

• The script uses ES7's async / await
• regeneratorRuntime is not known on the browser, you need to install @ babel / plugin-transform-runtime plugin

solution:

• Install @ babel / plugin-transform-runtime plugin

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

 

      Finally, modify the "plugins" in the .babelrc file: ["@ babel / plugin-transform-runtime"]
