In earlier versions of Go, 'go get' was used to build and install packages.
Now, 'go get' is dedicated to adjusting dependencies in go.mod. 'go install'
may be used to build and install commands instead. When a version is specified,
'go install' runs in module-aware mode and ignores the go.mod file in the
current directory. For example:

go install example.com/[email protected]
go install example.com/pkg@latest

See 'go help install' or https://golang.org/ref/mod#go-install for details.
