I’m trying to build Istio following the instructions at Preparing for Development · istio/istio Wiki (github.com) + Using the Code Base · istio/istio Wiki (github.com).
I can get as far as make build, but I keep failing at the next step:
$ go run ./istioctl/cmd/istioctl install
build istio.io/istio/istioctl/cmd/istioctl: cannot load embed: malformed module path "embed": missing dot in first path element
I’m very inexperienced with go, and completely inexperienced with building Istio, so don’t really know how to go about fixing things. Anyone able to help/recommend how to fix it?
Full output:
