From the README:

Installation

TSBS is a collection of Go programs (with some auxiliary bash and Python
scripts). The easiest way to get and install the Go programs is to use
go get and then make all to install all binaries:

# Fetch TSBS and its dependencies
$ go get github.com/timescale/tsbs
$ cd $GOPATH/src/github.com/timescale/tsbs
$ make

Using go 1.21.3, go get github.com/timescale/tsbs returns

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'.
