Rule can have only one resource error on yarn electron:serve

This issue sprung up when trying to get Frappe Books to work on an M1 laptop by switching sqlite3 source repo. (ref)

If you are facing this issue (which I'm certain you are) then this sequence of commands should get it running:

# Running this will create two folders in [pwd]

# Setting up local frappejs
git clone https://github.com/frappe/frappejs
cd frappejs && yarn && yarn link
cd ..

# Setting up books
git clone https://github.com/frappe/books
cd books && yarn upgrade frappejs && yarn link frappejs

# Running books in develop
yarn electron:serve

The important line above is yarn upgrade frappejs without which you'll still face the issue. Will close this when it's been fixed.
