ruby on rails - Can't install a npm module with webpacker-react -


i install react-dropzone in project. use react-rails project. had installed webpacker-react use gem. installed react-dropzone via npm install, can't load in react components. (i suppose it's due webpacker-react). so, how load modules installed via npm react components?

component.jsx

import dropzone 'react-dropzone'  class main extends react.component {      ondrop(file) {      }     render() {         return (             <div classname="container">                 <div>                     <dropzone ondrop={this.ondrop().bind(this)}>                         <p>to fix</p>                     </dropzone>                 </div>             </div>         )     } }

package.json (well installed)

"react-dropzone": "^3.13.3",

error message in firefox console:

referenceerror: require not defined in debugger : var _reactdropzone = require('react-dropzone');
