How to Set GOPATH on Mac OSX?

Setting $GOPATH on Mac OSX

Problem Statement:
When attempting to run Go example code, an error is encountered indicating that the GOPATH environment variable is unset.

Solution:

For the Shell:

1. Ensure that your ~/.bash_profile file includes the following lines:

   export GOPATH=$HOME/go
   export PATH=$GOPATH/bin:$PATH

   Copy after login

   Note: Use "$" symbols only at the appropriate places as shown.

For Sublime Text:

1. Navigate to: Sublime Text menu > Preferences > Package Settings > GoSublime > Settings: User

2. Add the following JSON to the file:

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

   Copy after login

   Replace "#USERNAME#" with your actual username.

3. Ensure that your GOPATH is set to the root of your Go folder (where src, pkg, and bin reside), not the full path to a specific package.

Important Note:

As of Go 1.8 (released Feb 2017), the GOPATH is automatically determined by the Go toolchain. It defaults to $HOME/go on Mac OSX. This simplifies the setup process and allows you to start using Go immediately.
