A continuation of #849. While the command no longer crashes, it now seems to hang indefinitely on both of my devices. It looks like this is related to something to do with the alpine edge repo, rather than 3.12. Exported rootFS is at the link below, as unfortunately it's too big for GH file upload.

npm install --save-dev --exact prettier

rootfs

You can easily reproduce this from scratch by doing the following:

1. Import a new rootfs.
2. Edit /etc/apk/repositories to point to edge instead of v3.12.
3. apk update && apk upgrade --available.
4. apk add npm nodejs.
5. Run the above command.
