Note: I made some changes in https://github.com/fiorix/go-diameter in my vendor dependency folder but still, I am unable to compile it.

Have you tried `go build -mod=vendor`? This will load your dependencies from `vendor` package instead of finding them in global GOPATH — Oleksii Miroshnyk, Apr 04 '20 at 14:13
There are tricks you can try and that might even work, but to know really the exact reason on why it's happening, I need some additional info. Can you once check if the said packages exist in the vendor directory. Also, share the output of `go env` and `go version`. — shmsr, Apr 04 '20 at 14:34

If you are outside GOPATH and do not use go modules and still trying to compile your project by using vendor folder, it is worth to try:

go build -mod=vendor

This prevents finding dependencies in the global GOPATH and will load your dependencies directly from vendor folder.
