Step by step configuration of Golang environment: Detailed deployment and installation guide

In this article, I will introduce to you how to deploy and install the Golang environment step by step. Go language is an efficient, concise and powerful programming language. It is widely used in back-end development, system programming and other fields. With this tutorial, you will be able to easily configure your Golang environment and be ready to start developing with the language.

Step 1: Download and install Golang

First, we need to download the Go language installation package from the Golang official website (https://golang.org/). Select the corresponding installation package according to your operating system, such as Windows .msi file, macOS .pkg file or Linux .tar.gz file.

After the download is completed, double-click to run the installation file and follow the prompts to complete the installation step by step. In Windows and macOS, the installation process usually just clicks "Next" to complete.

Step 2: Configure environment variables

After the installation is completed, we need to configure the system's environment variables to let the system know the installation path of the Go language. Next, we take the Windows system as an example to illustrate the specific configuration process.

1. Right-click "This PC" on the desktop and select "Properties".
2. Click "Advanced System Settings".
3. Select the "Advanced" tab in the System Properties dialog box, and then click the "Environment Variables" button.
4. Find the variable named "Path" in "System Variables" and double-click it.
5. Click the "New" button and add the installation path of the Go language, such as "C:Go in".
6. Click "OK" to save changes.

Step 3: Verify installation

Open the command line window and enter the following command to verify whether the Go language is successfully installed:

go version

If the command can run successfully and output Go If the language version information is displayed, the installation is successful.

Step 4: Configure GOPATH

Next, we need to configure the GOPATH environment variable to specify the directory in which the Go compiler saves the Go language source code files, dependency packages and compiled files. executable file.

1. Create a new workspace directory, such as "C:GoWorkspace".
2. Add the GOPATH variable to the environment variable and specify it as the workspace directory created in the previous step.

Step 5: Write and run the Go program

Now that we have completed the deployment and configuration of Golang, let us write a simple Go program and run it. Open any text editor and enter the following code:

package main

import "fmt"

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

Save the code as a "hello.go" file, then switch to the directory where the file is located on the command line and run the following command:

go run hello.go

If everything goes well, you will see the output as "Hello, Golang!".

So far, we have completed the Golang deployment and installation tutorial. I hope this tutorial can help you and let you start developing using Go language smoothly. Happy programming!
