I was trying to install a specific go version on my workstation by specifying the semantic version. What I meant by semantic versioning is the version number of the form <major>.<minor>.<patch>. For instance, to install go version go1.13.4 I was trying this:
brew install go@1.13.4
No luck! It says  Error: No available formula with the name "go@1.13.4"
