Getting Started: go get won't work any more

[march1993]

$ go get -d github.com/ortuman/jackal
go: go.mod file not found in current directory or any parent directory.
        'go get' is no longer supported outside a module.
        To build and install a command, use 'go install' with a version,
        like 'go install example.com/cmd@latest'
        For more information, see https://golang.org/doc/go-get-install-deprecation
        or run 'go help get' or 'go help install'.

That means you're not in your project directory. Go to your project directory, make sure it's using modules, then run that again. If you're not familiar with modules, you'll need to do a go mod init mymodule.com/whatever in your project folder first. This tutorial can get you started: https://go.dev/doc/tutorial/create-module

When I'm in my project directory. Command 'go get' runs successfully. But cd $GOPATH/src/github.com/ortuman/jackal fails since neithor GOPATH nor GOROOT is set.

Ahhh, you're talking about the installation instructions. That wasn't mentioned in your original post. Yes, those are now out of date.
