How to Resolve the '$GOPATH Not Set' Issue on macOS?

Resolving "$GOPATH Not Set" Issue on macOS

In the realm of Go programming, the $GOPATH environment variable plays a crucial role in configuring the toolchain. However, Mac OSX users often encounter the "cannot set $GOPATH" error when attempting to set up their workspace.

The Gist of the Problem

For Go to locate third-party packages, it requires a designated GOPATH. By default, this path is unset on macOS, leading to difficulties running code that relies on external repositories.

Addressing the Issue

Method 1: Automatic GOPATH Determination (Go 1.8 and Later)

Starting with Go 1.8, the Go toolchain simplifies the process by automatically setting GOPATH to $HOME/go on macOS. This eliminates the need for manual configuration in most cases.

Method 2: Manual Configuration via Terminal (For All Go Versions)

For those using Go versions prior to 1.8 or who prefer manual configuration, here are the steps:

• Edit the ~/.bash_profile file.

• Add the following lines:

  • export GOPATH=$HOME/go
  • export PATH=$GOPATH/bin:$PATH
• Save and source the file (. ~/.bash_profile).

Method 3: Configuration for Sublime Text

For users working in Sublime Text:

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

• Add the following JSON object:

  • {

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

    }

• Replace #USERNAME# with your actual username.

Additional Tips

• Ensure the GOPATH is set to the root of your Go folder, not the full path to the specific package.
• Consider using GoSublime for an enhanced Sublime Text workflow.
