Detailed explanation of golang installation method

Golang is a modern programming language that can greatly improve developer productivity and programming efficiency. In order to write and run programs using Golang, Golang must be installed on your computer. This article will introduce how to install Golang.

1. Determine the operating system

Before installing Golang, you first need to determine whether the operating system you are using is 32-bit or 64-bit. Under Windows systems, you can right-click "Properties" on "Computer" and select "System Type" to view it. Under Mac OS X system, you can check the operating system type in "About This Mac". Under Linux system, you need to run the command line command "uname -m". If the output result is x86_64, it means that the operating system is 64-bit.

2. Download the Golang binary file

The first step in installing Golang is to download the binary file. On the Golang official website, you can find the Golang binary file download page. According to your own operating system and computer processor architecture, select the appropriate Golang binary file to download.

3. Installing Golang

After the download is completed, you can start installing Golang. Under Windows systems, just double-click the downloaded binary file and follow the prompts to install it. Under Mac OS X, double-click the downloaded file to automatically decompress it and drag it to the application folder to complete the installation. Under the Linux system, you need to enter the following code on the command line:

sudo tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz

Among them, $VERSION represents the version number of Golang, $OS represents the operating system used, and $ARCH represents the processor architecture. For example, the command to install Golang v1.16.5 under Linux is as follows:

sudo tar -C /usr/local -xzf go1.16.5.linux-amd64.tar.gz

4. Configure environment variables

After installing Golang, you need to add the Golang binary file path to the system PATH environment variable in order to run Golang programs in the command line. Under the Windows system, you can click "Advanced System Settings" in the "My Computer" properties, then click "Environment Variables", find PATH in the system variables, click "Edit", and add the Golang binary file in the editing window path.

In Linux and Mac OS X systems, you need to add the Golang binary file path to the .bashrc or .profile file. Run the following command in the command line:

export PATH=$PATH:/usr/local/go/bin

Then run the following command to make the modification effective:

source ~/.bashrc

Or:

source ~/.profile

5. Check whether the installation is successful

After completing the above steps, you can run the following command in the command line to check whether the installation of Golang is successful:

go version

If the version number of Golang is output, the installation is successful.

Summary:

Golang is an increasingly popular programming language, and installing Golang is also a fairly simple matter. As long as you download the correct Golang binary file, and correctly install and configure the environment variables, you can start writing and running Golang programs on your computer.
