create-react-native-app fails to create project on Ubuntu with yarn

Description

I’m having errors trying to initialize a react-native app with this package.

Expected Behavior

If I run create-react-native-app Sauce , it should generate all the files needed for the app.

Observed Behavior

It throws an error while getting the files, then generates only a package.json file

What actually happened when you performed the above actions? It didn’t work.

If there’s an error message, please paste the full terminal output and error message in this code block:

I just tried create-react-native-app for the first time today, and experienced the same behavior/error on macOS High Sierra + Node 9.3.0 (installed with nvm) 🤔

Looks like something was going wrong during the “Fetching packages” phase of the initial yarn add. The progress bar was stuck at 441/442 for a while (almost like 438/439 for @leksyib), then the same unhandled ENOENT error stopped the process.

Weirdly enough, after a little frustration and a few retries, the process went through to the yarn install part, and finally succeeded up to the “Happy hacking!” message.

I am almost sure that the auth0-js dependency is not the culprit. It just happens to be a module that shows a warning just before the real error happens.

I do believe, though, that the error has to do with some sort of unhandled network fetch timeout, my current Internet connection being particularly bad, and the process finally going through after a few tries. It could be helpful it this was better handled by either create-react-native-app or yarn.

Hope this helps.
