How to set up a Golang development environment

Golang is a simple and easy-to-use programming language that is highly respected for its efficient performance and smaller code size compared to other languages. Today we will discuss how to set up a Golang development environment on your own computer to prepare for your programming journey.

Step one: Download Golang

First you need to download the Golang installation package, so you need to download the latest version from the Golang official website (https://golang.org/dl/) Golang binaries. After opening the link, select the file suitable for your operating system to download. The Golang compiler is currently supported on most operating systems, including Windows, macOS, and various Linux distributions.

Step 2: Install Golang

When you download the Golang installation file, the installation process is very simple. Double-click the downloaded binary file, such as "go1.16.2.windows-amd64.msi" under the Windows platform, and then follow the prompts to install it.

During the installation process, please be sure to add the Golang binary file path to the system path. Doing this will allow the operating system to correctly find the installed Golang binary and eliminate the need to reset the environment variables each time it is used. If you don’t know how to add the installation path to the system path, you can follow these steps:

1. Open "The System Properties" panel, open the "Advanced" tab
2. Click "Environment Variables" button, open the user or system environment variable editing panel
3. In the editing panel, find the Path property in the "System Variables" list, click the edit button
4. In the editing window Add Golang installation path. For example: "C:\Go"

After completing the above steps, you can use the "go" command directly from the command line when using the Golang compiler.

Step 3: Test Golang

Once Golang is installed, we need to test whether the installation is successful. To do this, open a command line terminal and enter the following command:

go version

If you see results similar to the following output from the terminal, you have successfully installed Golang.

go version go1.16.2 windows/amd64

If you don't see similar output, you need to reinstall Go and make sure the environment variables are configured correctly.

Step 4: Choose an editor

To start writing Golang code, you need to choose an editor with integrated Golang language support. Next, we recommend several easier-to-use editors:

1. Visual Studio Code: This is a popular editor with rich functions and Golang language support. If you want to use this editor, you can first install the "Go" extension, which provides many useful tools.
2. GoLand: This is an integrated development environment (IDE) developed by JetBrains with many advanced features and software engineering practice support. It has rich Golang language support to improve developer efficiency.
3. Sublime Text: This is a lightweight editor, but it is also a flexible and easily extensible editor. If you want to use Sublime Text as your Golang editor, you can install the Golang language package to support Golang language writing.

4. Summary

As a fast, simple and easy-to-use programming language, Golang is becoming more and more popular among developers. Through the introduction of this article, you can quickly download, install and configure the Golang development environment. Now, you can try writing your first Golang program.
