What should I run so I can run the tests?

[retorquere]

I've ran

npm run babel
npm run nearley
npm run astrocite
npm test

but I still get

Error: Cannot find module './grammar'

Can you run tree or something similar on the src directory so I can compare?

[larsgw]

Actually, I think it's just that npm run babel should be done last as it has to copy the generated grammar.js files.

[retorquere]

npm run babel && npm test

seems to do the job (at least I see no error, still waiting for output)

might be convenient to add

"pretest": "npm run babel"

to package.json

Yeah, I noticed I forgot to as well. Usually I have @babel/register for tests.
