Kperf build failing

I've tried to Build kperf by running build.sh, but I get The following error with unable to find io/fs. I'm a huge go noob, any help appreciated.

🔥 Failure

Steps to reproduce:

1. Create and cd into /kperf/src/knative.dev directory
2. Clone Kperf project
3. cd into kperf project directory and run ./hack/build.sh

The error message means that your Go tool

• does not support -mod=mod (module support was introduced as an experimental feature in Go1.11).
• does not have the package io/fs (which was added in Go1.16).

That indicates the Go tool installed on your system is too old.

According to the go directive in the go.mod file, I think you should upgrade to Go1.18 at least.

module knative.dev/kperf

go 1.18

It's better to install the latest Go. See https://go.dev/doc/install
for the installation instructions.
