Cannot set $GOPATH on Mac OSX

Question

I'm trying to set my $GOPATH variable to run some example code on my machine:

$ smitego-example go run main.go  main.go:5:2: cannot find package "github.com/#GITHUB_USERNAME#/smitego" in any of:     /usr/local/go/src/pkg/github.com/#GITHUB_USERNAME#/smitego (from $GOROOT)     ($GOPATH not set)  $ smitego-example export $GOPATH=$HOME -bash: export: `=/Users/#OSX_USERNAME#': not a valid identifier 

Contents of github.com/#GITHUB_USERNAME#/smitego/smitego.go:

package smitego 

How can I set my GOPATH so it works always and forever?

Answer 1

Update, as of Go 1.8: If you're installing Go 1.8 (released: Feb 2017) or later, GOPATH is automatically determined by the Go toolchain for you.

It defaults to $HOME/go on macOS (nee OS X) - e.g. /Users/matt/go/. This makes getting started with Go even easier, and you can go get <package> right after installing Go.

For the shell: (the manual method)

~/.bash_profile should contain export GOPATH=$HOME/go and also export PATH=$GOPATH/bin:$PATH. The use of the $ is important: make sure to note where I've used it (and where I have not).

For Sublime Text:

Sublime Text menu > Preferences > Package Settings > GoSublime > Settings: User

{         "shell": ["/bin/bash"],         "env": {"GOPATH": "/Users/#USERNAME#/go/"}, } 

Make sure your GOPATH is not set to the full path of the package; just the root of your go folder where src, pkg, and bin reside. If you're not using GoSublime, I'd suggest installing that first.
