Troubleshooting GOPATH Configuration on Mac OS X 10.10

When setting up Go development on Mac OS X 10.10, users may encounter issues related to GOPATH configuration. This article provides guidance on resolving these problems and establishing the correct environment variables.

Setting GOROOT and PATH

GOROOT should point to the directory where Go is installed, not the executable itself. Correctly set it as follows:

export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

Setting GOPATH

GOPATH should reference a folder containing src, pkg, and bin directories. It should not directly reference the src folder. For example:

export GOPATH=/Users/USERNAME/Documents/GoProjects

Bash Configuration

Add the GOPATH setting to your ~/.bashrc file using export. Ensure that you are using a bash shell by verifying the output of 'echo $SHELL'.

Go Environment Variables

Use 'go env' to check the current values of Go environment variables, including GOPATH.

Avoid Sudo

Do not use 'sudo go get' as the environment variables set for the root user (sudo) will not be the same as those for your current user. Instead, execute:

go get github.com/gocql/gocql

Additional Notes:

• You may not need to explicitly set GOROOT if you have installed Go through Homebrew.
• If issues persist, check the $GOPATH folder permissions and ensure they are set to allow write access for your user.
