If it isnât the go command at /usr/local/go/bin/go, you need to fix your executable path. On Mac OS and other Unix-like systems, use which go to see the go command being executed, if any. If you get an error instead of the version message, itâs likely that you donât have go in your executable path, or you have another program named go in your path. (Darwin is the name of the kernel for Mac OS and amd64 is the name for the 64-bit CPU architecture from both AMD and Intel.) This tells you that this is Go version 1.15.2 on Mac OS. If everything is set up correctly, you should see something like this printed: go version go1.15.2 darwin/amd64 You can validate that your environment is set up correctly by opening up a terminal or command prompt and typing: $ go version Install the Go development tools only on computers that build Go programs. "/gorilla/mux" // Your imported package "net/http"įunc yourHandler(w http.ResponseWriter, r *http.Go programs compile to a single binary and do not require any additional software to be installed in order to run them. You can then use this package in your Go programs like this: package main The command above will import the package mux into this directory $GOPATH/src//gorilla/mux. To do so you'll use the go get command: go get -u /gorilla/mux Since you have $GOPATH/bin added to your $PATH, you can run your program from anywhere: $ helloīesides creating your own packages you can import and use other packages in your Go code. If you wish to compile it and move it to $GOPATH/bin, then run: go install.
Run the program by running: $ go run hello.go
Write your first programĬreate a file in your workspace $GOPATH/src/hello/main.go and add some code, for example: package main bash_profile your current session or simply open new tab within iTerm. export GOPATH=/something-elseĪdd GOPATH/bin directory to your PATH environment variable so you can run Go programs anywhere. If you really want to change your GOPATH to something else add GOPATH to your shell/bash/zsh initialization file. It defaults to a directory named go inside your home directory ( $HOME/go). The GOPATH environment variable specifies the location of your workspace. Setup your workspace The GOPATH and PATH environment variables When installed, run go version to see the installed version of Go. You can follow the official instructions on how to install Go, or you can use Homebrew instead: brew install go Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
