Install the Go tools
If you are upgrading from an older version of Go you must first remove the existing version.
macOS package installer
Download the package file, open it, and follow the prompts to install the Go tools. The package installs the Go distribution to /usr/local/go
.
The package should put the /usr/local/go/bin
directory in your PATH
environment variable. You may need to restart any open Terminal sessions for the change to take effect.
Test your installation
Check that Go is installed correctly by setting up a workspace and building a simple program, as follows.
Create your workspace directory, $HOME/go
. (If you’d like to use a different directory, you will need to set the GOPATH
environment variable.)
Next, make the directory src/hello
inside your workspace, and in that directory create a file named hello.go
that looks like:
package main
import "fmt"
func main() {
fmt.Printf("hello, world\n")
}
Then build it with the go
tool:
$ cd $HOME/go/src/hello
$ go build
The command above will build an executable named hello
in the directory alongside your source code. Execute it to see the greeting:
$ ./hello
hello, world
If you see the “hello, world” message then your Go installation is working.
You can run go
install
to install the binary into your workspace’s bin
directory or go
clean
-i
to remove it.
