Installation on go1.19.4

[karlfunk-ydb]

Required Caveat: am a GO novice, this is my first GO programming....

Have just installed go1.19.4 on my mac

go version go version go1.19.4 darwin/amd64

Following the instructions in this projects wiki I try to install using go get github.com/jackc/pgx/v5

Which results in:

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'.

Trying go install github.com/jackc/pgx/v5@latest

Results in:

go: downloading github.com/jackc/pgx/v5 v5.2.0 go: downloading github.com/jackc/pgx v3.6.2+incompatible go: downloading github.com/jackc/pgpassfile v1.0.0 go: downloading golang.org/x/crypto v0.0.0-20220829220503-c86fa9a7ed90 go: downloading github.com/jackc/pgservicefile v0.0.0-20200714003250-2b9c44734f2b go: downloading golang.org/x/text v0.3.8 package github.com/jackc/pgx/v5 is not a main package

What is my easiest path forward?

go: go.mod file not found in current directory or any parent directory.

Did you run go mod init in your current directory?

That works!
Sorry, I get the feeling this was a really dumb Q...

Thanks.
