How do I set GOPATH on Mac OS X 10.10 for Go package installation?

Setting GOPATH in Mac OS X 10.10

When attempting to install Go packages, users may encounter errors indicating that $GOPATH is not set. Proper configuration of GOPATH is crucial for accessing Go modules and libraries.

To ensure proper GOPATH setup:

Set GOROOT and PATH:

• GOROOT: Refers to the Go installation directory, typically the folder where Go is installed. Do not set it to the path of the Go executable.
• PATH: Add the $GOROOT/bin directory to the PATH environment variable to enable access to Go commands.

Set GOPATH:

• GOPATH: Refers to the workspace directory where Go source code, compiled packages, and binaries reside. It should contain the subdirectories src, pkg, and bin.

Specific Instructions:

• Set GOPATH to a directory under which the src, pkg, and bin subdirectories exist.
• Avoid setting GOPATH directly to the src folder.
• Ensure GOPATH is set in your shell using export.
• Check that you're using a bash shell, not fish or another shell.
• Verify the output of go env to confirm that GOPATH is set correctly.
• Do not install Go packages using sudo go get as it can interfere with environment variables. Instead, use go get.
