Before we set up a GO locale, we need to understand some basic concepts and preparations. Go, also known as Golang, is a statically typed, compiled programming language with a concise syntax and powerful concurrency processing capabilities. Here are the steps to set up a Go locale:
1. Install the GO locale.
First of all, you need the official *** installation package for your operating system from Go Language. For Windows users, you can select the Windows executable installation package (.).msi）；For Mac users, you can choose the Mac OS X installation package (.).pkg）；For Linux users, you can select the **Linux Archive (.).tar.gz）。
*Once completed, follow the instructions of the installation wizard to install it. During the installation process, you need to select the appropriate installation directory and set the environment variables. Make sure to add the go installation directory to the system environment variables so that you can access go-related commands directly from the command line.
2. Verify the installation.
Once the installation is complete, we need to verify that the Go language is successfully installed. Open the command-line terminal and enter the following command:
shellgo version
If the GO language is successfully installed, the terminal will display an output similar to the following:
shellgo version go1.15.6 darwin/amd64
This means that you have successfully installed the Go language on your system with version number 115.6。
3. Set gopath and goroot
GoPath is the ** workspace for the Go language, which is used to store third-party libraries and projects for the Go language. goroot is the installation directory of the go language. In earlier versions of go, you needed to manually set the gopath and goroot environment variables. But in go 1In 11 and later, go module support was introduced, which automatically manages dependencies, so the settings of gopath and goroot become less important.
However, in order to be compatible with earlier versions of the Go project and third-party libraries, we still need to set the gopath environment variable. Enter the following command in the command-line terminal:
shellexport gopath=$home/go
This will set the gopath to the go folder in your user directory. You can change the path to your liking.
4. Create a GO project.
Now that we've set up the Go locale, let's create a simple Go project to test it out. Go to the directory where you want to store your project in the command line terminal, and then use the following command to create a new go project:
shellmkdir myproject
cd myproject
Then, create a file called maingo's source file and enter the following:
gopackage main
import "fmt"
func main()
fmt.println("hello, world!")
This is a very simple GO program that will output in the terminal"hello, world!"。Once the file is saved, compile and run the program with the following command:
For Windows users:
shellgo run main.go
For Mac and Linux users:
shellgo run main.go
