Thanks! When adding brew installations, it's a good idea to check if anything else needs to be done by running brew info [name of tool]. For example, here is the output of brew info go:

go: stable 1.4.2 (bottled), HEAD
https://golang.org
Not installed
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/go.rb
==> Options
--with-cc-all
    Build with cross-compilers and runtime support for all supported platforms
--with-cc-common
    Build with cross-compilers and runtime support for darwin, linux and windows
--without-cgo
    Build without cgo
--without-godoc
    godoc will not be installed for you
--without-vet
    vet will not be installed for you
--HEAD
    Install HEAD version
==> Caveats
As of go 1.2, a valid GOPATH is required to use the `go get` command:
  https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/go/libexec/bin

Note the last part. If you could please add that and test that it works, that would be great.

You can do it like this:

# shellcheck disable=SC2016
append_to_file "$HOME/.zshrc" 'export PATH="$PATH:/usr/local/opt/go/libexec/bin"'
