How Can I Set Multiple GOPATH Directories in Go?

Setting Multiple GOPATH Directories

In Go, you can customize your workspace by setting multiple directories for GOPATH. This allows you to separate different projects and keep your workspace organized.

Problem Statement

A developer has set GOPATH to "/Users/me/dev/go" and has created multiple go projects under "/Users/me/dev/go/src." However, they are not satisfied with having a single "go" directory in their root dev folder that contains all their client projects.

Solution

Yes, it is possible to have multiple GOPATH directories. GOPATH is essentially a list of directories, similar to PATH. You can set different GOPATH directories by modifying your environment variables.

For Linux users:

export GOPATH="/home/peter/gopath:/home/peter/public/gopath"

For Windows users:

set GOPATH="C:\gopath;C:\public\gopath"

Remember to use ";" as the path separator on Windows and ":" on Linux.

Note

When using go get, it will automatically download packages to the first directory specified in your GOPATH. To change this behavior, you can use the -d flag to specify the target directory explicitly.

To verify your changes, run go env to check your GOPATH settings. This will display the GOROOT and GOPATH directories.
