/usr/local/lib/node_modules/create-react-app/node_modules/path-exists/index.js:2
const fs = require('fs');
^^^^^

Can you please specify your Node version?

[gaearon]

As noted in README we only support Node 4 and higher. Please update your Node version, the project won't work without it.

We should however make sure that CLI doesn't just throw, and print a descriptive error on earlier versions instead. I think this is a regression because we added a dependency on path-exists which seems to need Node 4 itself. So we need to replace this dependency in global CLI with something that works on Node 4 so we can print a proper warning.

Did you mean "with something that works on Node 4 and below"?

If so, path-exists is a very simple module that we can probably write ourselves in ES5 and just put it somewhere as a file to require, if that makes sense. We don't have to worry about the promise or any async methods as CRA doesn't use them.

Sounds good, yes this is what I meant.

[abhinavkumar940]

That was indeed the issue. Upgraded to 6.5 and it now works.
Thank you for the prompt response, guys.

@sotojuan Would you be interested in sending a PR to make CLI work on earlier nodes, at least up to the point where it detects the version?
