process.binding is not supported

[jfm10]

I just installed markdown-pdf with the next npm sentence:
npm install markdown-pdf --ignore-scripts

Then, I just declare a variable like this:
var markdown = require('markdown-pdf')

I started my react web app and the browser shows next error:

Error: process.binding is not supported
▶ 32 stack frames were collapsed.
This screen is visible only in development. It will not appear if the app crashes in production.
Open your browser’s developer console to further inspect this error.

Please, help. Sorry for my english.
