Where exactly did you create the folder testmux? What were the exact
commands that you ran? What was the exact output?
I tried to follow your direction.

go: cannot determine module path for source directory /tmp/x (outside
GOPATH, module path must be specified)
Example usage:
'go mod init example.com/m' to initialize a v0 or v1 module
'go mod init example.com/m/v2' to initialize a v2 module
Run 'go help mod init' for more information.
What did you see when you ran "go mod init"?
