Grafana building from source error (undefined: server.Initialize)

How is this working on Windows 10? Everytime i try to run

make gen-go

i get the error: File *.sh not found.
process_begin: CreateProcess(NULL, # Install binary/ries using Go 1.14+ build command. This is using bwplotka/bingo-controlled, separate go module with pinned dependencies., …) failed.
m

Thanks a lot,
Thomas
