x/mobile: wiki page commands don't work

What version of Go are you using (go version)?

$ go version
go version go1.18.1 linux/amd64

Does this issue reproduce with the latest release?

Probably.

What operating system and processor architecture are you using (go env)?

What did you do?

Went through the guide on the wiki page: https://github.com/golang/go/wiki/Mobile

$ gomobile init
gomobile: command not found

had to do echo 'export PATH=$PATH:~/go/bin' >> ~/.bashrc && . ~/.bashrc (from #21818 comments). Didn't see this documented anywhere.

$ go get -d golang.org/x/mobile/example/bind/...
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'.

Tried a whole bunch of things:

$ go install golang.org/x/mobile/example/bind/...
go: warning: "golang.org/x/mobile/example/bind/..." matched no packages
$ go install golang.org/x/mobile/example/bind/
go: 'go install' requires a version when current directory is not in a module
        Try 'go install golang.org/x/mobile/example/bind/@latest' to install the latest version
$ go install golang.org/x/mobile/example/bind/@latest
go: golang.org/x/mobile/example/bind/@latest: argument must be a clean package path

Still not sure what to do at this point.

What did you expect to see?

I expected the commands in the wiki page to work correctly out of the box.

What did you see instead?

They did not work out of the box, and no documentation is provided for how to solve the issues encountered. Just a poor experience for new users overall.

According to the provided messages, it seems that gomobile is not yet installed on your environment, try:

go install golang.org/x/mobile/cmd/gomobile@latest

This is described in https://github.com/golang/go/wiki/Mobile#tools
