Go Language Environment Installation

Go language supports the following systems:

The installation package download address is: https://golang.org/dl/.

If you cannot access the above link, you can use this address: https://golang.google.cn/dl/.

The package names corresponding to each system are:

Operating System Package Name
Windows go1.4.windows-amd64.msi
Linux go1.4.linux-amd64.tar.gz
Mac go1.4.darwin-amd64-osx10.8.pkg
FreeBSD go1.4.freebsd-amd64.tar.gz

UNIX/Linux/Mac OS X, and FreeBSD Installation

The following describes the installation method using source code on UNIX/Linux/Mac OS X, and FreeBSD systems:

  1. Download the binary package: go1.4.linux-amd64.tar.gz.

  2. Extract the downloaded binary package to the /usr/local directory.

    tar -C /usr/local -xzf go1.4.linux-amd64.tar.gz

  3. Add the /usr/local/go/bin directory to the PATH environment variable:

    export PATH=$PATH:/usr/local/go/bin

The above method only temporarily adds PATH, and it will be lost after closing the terminal.

You can edit ~/.bash_profile or /etc/profile and add the following command to the end of the file for a permanent effect:

export PATH=$PATH:/usr/local/go/bin

After adding, you need to execute:

source ~/.bash_profile
or
source /etc/profile

Note: On Mac systems, you can use the .pkg installation package to complete the installation by double-clicking, and the installation directory is /usr/local/go/.

Windows System Installation

On Windows, you can use the .msi suffix (found in the download list, such as go1.4.2.windows-amd64.msi) installation package to install.

By default, the .msi file will install in the c:\Go directory. You can add the c:\Go\bin directory to the Path environment variable. You need to restart the command window for the changes to take effect.

Installation Test

Create a working directory C:>Go_WorkSpace.

test.go file code:

package main

import "fmt"

func main() {
   fmt.Println("Hello, World!")
}

Execute the above code using the go command, and the output is as follows:

C:\Go_WorkSpace>go run test.go

Hello, World!
