u like the environment management idea, write me a simple scenario for this kind of problem

Sure, here's a simple scenario for the environment management problem:

Suppose you are working on a Go project that requires the use of a specific version of Go. In your development environment, you have Go installed, but the version installed is not the one you need for your project. To solve this problem, you can create a script that sets up the environment by downloading and installing the required version of Go.

Here's an example of how you can implement this solution using the os/exec package in Golang:

package main

import (
"fmt"
"os"
"os/exec"
)

func main() {
// Check if the required version of Go is already installed
cmd := exec.Command("go", "version")
out, err := cmd.CombinedOutput()
if err != nil {
fmt.Println("Go version not found. Installing...")

// Download and install the required version of Go
cmd = exec.Command("curl", "-L", "https://dl.google.com/go/go1.19.2.linux-amd64.tar.gz")
err = cmd.Run()
if err != nil {
fmt.Println("Error downloading Go version:", err)
return
}

cmd = exec.Command("tar", "-xzvf", "go1.19.2.linux-amd64.tar.gz")
err = cmd.Run()
if err != nil {
fmt.Println("Error extracting Go version:", err)
return
}

cmd = exec.Command("mv", "go1.19.2", "go")
err = cmd.Run()
if err != nil {
fmt.Println("Error moving Go version:", err)
return
}

fmt.Println("Go version installed successfully!")
} else {
fmt.Println("Go version found.")
}
}
In this script, we first check if the required version of Go is already installed by running the "go version" command. If the version is not found, we download and install the required version of Go using "curl" and "tar". Finally, we move the extracted Go version to the "go" directory.

This script can be run in your CI/CD pipeline to ensure that the required version of Go is available in the environment before running your Go application.
