How Do I Fix the '$GOPATH not set' Error When Using `go get`?

Setting GOPATH to Fix "$GOPATH not set" Error

When attempting to install packages using "go get," you may encounter the error "cannot download, $GOPATH not set." This error indicates that the GOPATH environment variable, which specifies the directory used for Go packages, has not been set.

Setting GOPATH on macOS

To set GOPATH on macOS, do the following:

1. Open your terminal.
2. Execute the following command:

export GOPATH="$HOME/your-workspace-dir/"

3. Add the following line to your ~/.bashrc or equivalent shell configuration file:

export GOPATH="$HOME/your-workspace-dir/"

This will set GOPATH permanently for future use.

GOPATH Layout

Go installs packages under the following subdirectories within the GOPATH directory:

• src/: Source code for Go packages
• bin/: Compiled binaries
• pkg/: Compiled package objects

You should place your own packages under the $GOPATH/src** directory, organized according to their import paths (e.g., **$GOPATH/src/github.com/myusername/).

Additional Tips

• For faster navigation to package directories in bash, set CDPATH.
• Set GOPATH=$HOME to place Go's directories directly under your home directory.
