Error: Command failed: yarn build in builder app

When I try to build builder app… I get this error

I am trying it on version-15… Can I use frappe builder in version-15?
How to slove this problem?



Getting the same error on version 15, @Samsul were you able to resolve the problem?

@Douglas_muriuki Yes, I was able to solve this problem…
You can try by run this command

cd frontend && yarn build
