React prop-types error

I'm trying to create web app in codepen. I'm using React, ReactDOM. All was fine. But when I added react-router-dom to my project, I got an error:

react-router-dom.min.js:1 Uncaught Error: Cannot find module "prop-types"

How can I fix this?

Solution

  • As of React 15.5.0, PropTypes have been removed from the core React package as a separate dependency. To fix this, add prop-types into your code:

    If you're loading via script tags:

    <script src="https://unpkg.com/prop-types/prop-types.min.js"></script>

    Or via NPM:

    npm install --save prop-types
