@Samsul

Can I use frappe builder in version-15?

Yes.

Error during installation of "builder" app - ImportError

Hi @Masky, In version 14 of ERPNext, the ‘builder’ feature is not supported due to some issues related to dependencies. However, it works fine in version 15 and any version above 15. CC: @surajshetty Thank You!
