How to upgrade go from 1.4 to 1.5 via homebrew

Question

I try brew upgrade go

it always show:

go 1.4.1 already installed

how can i upgrade go to 1.5?

Answer 1

You should run brew update first, then run brew upgrade to upgrade all software installed by brew. Also you can run brew upgrade go to upgrade go only.

Answer 2

Try running

brew update
brew upgrade

brew install go --cross-compile-common

brew upgrade might upgrade go alone without having to try to install it, after you run brew update/upgrade try running go version and see which version you have.
