下载 go-redis 包时报错找不到包“github.com/go-redis/redis/v8”

Question

I tried to download go-redis using this command go get github.com/go-redis/redis/v8 but I got this following error :

cannot find package "github.com/go-redis/redis/v8" in any of:
        C:\Go\src\github.com\go-redis\redis\v8 (from $GOROOT)
        E:\Go Workspace\src\github.com\go-redis\redis\v8 (from $GOPATH)

Why did I get this error and how to fix this ?

OS : Windows
Go version : go version go1.15 windows/amd64

Following steps solved my problem:

1. Initialize the go module (since go-redis supports last 2 Go versions & requires support for Go Modules

go mod init github.com/my/repo

2. Install redis/v8 using the command

go get github.com/go-redis/redis/v8

Create a main.go file and write the following code to check for your connection

package main

import (
    "fmt"
    "github.com/go-redis/redis"
)

func main() {
    fmt.Println("Go Redis Connection Test")

    client := redis.NewClient(&redis.Options{
        Addr: "localhost:6379",
        Password: "",
        DB: 0,
    })

    pong, err := client.Ping().Result()
    fmt.Println(pong, err)

}

When we will run this now, we will see that the Go application will successfully ping the redis instance and it will return a successful PONG response:

go run main.go
