[gedw99]

generate for grpc is not running for me in https://github.com/rotemtam/ent-grpc-example/blob/main/ent/generate.go

here is a full run:

rm -rf ent-grpc-example
git clone https://github.com/rotemtam/ent-grpc-example

make: *** [gen] Error 1

I get this same error on other examples also, so its something i am not understanding maybe ?

the generate.go has :

package ent

//go:generate go run -mod=mod entgo.io/ent/cmd/ent generate ./schema
//go:generate go run -mod=mod entgo.io/contrib/entproto/cmd/entproto -path ./schema

and so i presume the -mod=mod ensures that these binaries get downloaded, and i dont have to do it.
