Please run:

npm install -g npm@latest

cd your_project_directory
rm -rf node_modules
npm install

and try to reproduce the issue again.

Can you still reproduce it?

[stephencelis]

I'm also seeing an issue with npm test and a freshly generated project: it hangs indefinitely. (Could it be an issue with watchman not finding any test files?)

Anything I can do to debug? npm is up to date and node_modules directory freshly generated.

@stephencelis

This issue is not about hanging, it's about a crash due to a missing preset. Could you please file a new issue with details about your setup and your console output / screenshot?

[stephencelis]

@gaearon Done! #960

Apologies for moving off topic!

[fadeojo]

@gaearon same result.
Couldn't find preset "es2015" relative to directory "/Users/fadeojo/Development/react" it's loking for the preset one dir up instead of /Users/fadeojo/Development/react/nethan

[gaearon]

I have a suspicion you might have a stray .babelrc file in one of the above directories.
If you do, delete it.

For example, make sure /Users/fadeojo/Development/react/.babelrc doesn't exist.

[fadeojo]

@gaearon you were right. This issue is resolved.

[gaearon]

Let's reopen because ideally .babelrc in parent directories should be ignored.
