[Build Fail] Cannot find module '../../validators/validate.js'

[agamsingh9]

Description

Following CONTRIBUTING.md, I get the following error running bun dev or ./packages/opencode/script/build.ts --single

error: Cannot find module '../../validators/validate.js' from '/home/agam/git/opencode/node_modules/.bun/@babel+types@7.28.5/node_modules/@babel/types/lib/builders/generated/lowercase.js'

Please offer guidance. I've been stuck for a while trying to install opencode.

@agamsingh9 are you trying to install opencode?

I've been stuck for a while trying to install opencode.

Why did you read contributing.md then? What does this have to do w/ installing?
