How to install Golang program

In the daily work of programmers, programming language is one of the most important tools. Go language (also known as Golang) is an emerging language that was developed by Google in 2007 and officially released in 2009. Since its release, it has become the first choice of many programmers (ranked fourth according to GitHub rankings), especially in web development, network programming, data analysis, artificial intelligence, etc.

This article will take you through how to install the Golang program and how to configure it under Windows and Linux operating systems.

Installation of Golang program

First, we need to download the installation package of the Golang program from the official website (https://golang.org/dl/). Select the corresponding system version (Windows, Linux or Mac OS X) and architecture (32-bit or 64-bit). If you have already downloaded the installation package, you can skip this step.

Installation under Windows

Step 1: Double-click the installation package to open the installation wizard. The installation wizard will ask you if you agree to abide by the agreement, as well as the location of the installation files and other information. Just choose according to your own needs.

Step 2: Add Golang to the system environment variables. Environment variables are lists used to store important information in the system. Here, we need to add the path of the Golang program to the PATH environment variable. If you don't know how to add environment variables, you can enter "environment variables" in the Windows search bar and choose to open "Edit System Environment Variables", then select the "Environment Variables" button, select "Path" in the system variables and click " Edit" and add the Golang path to the path list.

Step 3: Verify Golang installation. Open the command prompt (Win R key, enter "cmd", press Enter), enter "go help" in the command prompt to verify whether Golang is successfully installed. If the Golang help message appears, the installation is successful.

Installation under Linux

Step 1: Download the Golang program and unzip it. Unzip the downloaded Golang installation package to any folder. For convenience, we can extract it to the "/usr/local/go" folder. The decompression command is as follows: tar -C /usr/local -xzf go1.15.3.linux-amd64.tar.gz (the decompressed file name may be different, just replace it according to the actual situation).

Step 2: Add Golang to the PATH environment variable. We need to edit the "/etc/profile" file and add the following two lines of code at the end of the file to add Golang to the PATH environment variable:

export PATH=$PATH:/usr/local/go/bin
export GOPATH=/home/yourgopath # gopath目录

Step 3: Save the file and reload "/etc/profile" ". Enter the following command:

source /etc/profile

Step 4: Verify the installation of Golang. Open the terminal (Ctrl Alt T) and enter "go help" to verify whether Golang is successfully installed. If Golang's help information is displayed, the installation is successful.

Summary

Through the above steps, we have successfully installed the Golang program into the Windows and Linux operating systems and made the necessary configurations. Now you can develop using Golang according to your needs.

Here, you also need to note that some Unix-like systems, such as Mac OS X, require the same installation steps as Linux. In addition, if you are a Mac user, the installation process may be easier, because usually, Mac has the Golang program pre-installed. If Go cannot be found on the command line, you need to install it via the "brew install go" command.

Finally, there are more and more projects based on Golang. If you want to study in depth and know more about Golang, you can consider using some online courses and documents, such as Coursera's "Programming with Google Go" and Official website (https://golang.org/doc/). I wish you all a happy study!
