Gatsby uses yarn, not npm. This is noted in the README of the “www” submodule.

[ilyaryabchinski]

tried to remove node_modules and install dependencies again using yarn, the issue persists

[wardpeet]

Could you try the following:

1. remove node_modules
2. remove yarn.lock
3. remove package-lock.json

[ilyaryabchinski]

Still get the exception thrown from yoga-layout-prebuilt package

[LekoArts]

It works for me pulling down the latest version of the www repo so please try again and follow the steps from wardpeet if necessary.

Closing this as solved.
