go get is not working

There is an error when typing "go get github.com/akavel/rsrc" :
go.mod file not found in current directory or any parent directory.
'go get' is no longer supported outside a module.

There is an error when typing "go get github.com/akavel/rsrc" : go.mod file not found in current directory or any parent directory. 'go get' is no longer supported outside a module.

This is merely an issue of outdated documentation. Recent versions of go use go get as dependency management and no longer to install a program. To install a program, use go install, like so: go install github.com/akavel/rsrc.
