Go language environment installation

The Go language supports the following systems:

• Linux
• Freebsd
• Mac OS X (also known as Darwin)
• Window

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

The package name for each system:

UNIX/Linux/Mac OS X, and FreeBSD installations

Here's how to install using source code under UNIX/Linux/Mac OS X, and FreeBSD systems:

1, download the source package: go1.15.2.linux-amd64.tar.gz.

2. Unzip the downloaded source package to the /usr/local directory.

tar -C /usr/local -xzf go1.15.2.linux-amd64.tar.gz

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

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

4, verify whether the installation of successful commands:

$ go version

Note: Under MAC, you can use the installation package at the end of .pkg to double-click directly to complete the installation, the installation directory is under /usr/local/go/, and the installation path /usr/local/go/bin is configured into a variable environment.

Installed under the Windows system

Windows can be installed using an installation package with the .msi suffix, which can be found in the download list, such as go1.4.2.windows-amd64.msi.

By .msi files are installed in the c:\Go directory. Y ou can add the c:\Go\bin directory to the PATH environment variable. After you add, you need to restart the command window to take effect.

Install the test

Create a working directory, C:\gt;Go_WorkSpace.

File name: test.go, code as follows:

package main

import "fmt"

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

Use the go command to execute the above code output as follows:

C:\Go_WorkSpace>go run test.go

Hello, World!
