build command-line-arguments: cannot load github.com/gomodule/redigo: module github.com/gomodule/redigo@latest found (v2.0.0+incompatible), but does not contain package github.com/gomodule/redigo

can anyone help?
go version 1.13.11

[stevenh]

Are you using go mod, if not then that should fix this

yes, i am using go mod. does any other methods to fix this?

[stevenh]

What does your go.mod look like for redigo?

[justinian]

It looks like the existence of the tag v2.0.0 which doesn't have a go.mod (and seems pretty old?) causes Go to fail to pick up the current 1.x versions that have go.mod files. Without explicitly adding redigo to go.mod, Go auto-adds the following:

github.com/gomodule/redigo v2.0.0+incompatible

[stevenh]

Try removing any mention of github.com/gomodule/redigo from your go.mod and then running:
go get github.com/gomodule/redigo/redis

[bensema]

go mod init
go mod tidy
go get github.com/gomodule/redigo/redis@latest

[stevenh]

Your commands aren't quite right there @bensema it should be something like:

$ go mod init github.com/stevenh/redis-test
go: creating new go.mod: module github.com/stevenh/redis-test

$ go get github.com/gomodule/redigo/redis
go: downloading github.com/gomodule/redigo v1.8.2
go: downloading github.com/gomodule/redigo/redis v0.0.0-do-not-use
go: found github.com/gomodule/redigo/redis in github.com/gomodule/redigo v1.8.2

$ more go.mod
module github.com/steveh/redis-test

go 1.14

require github.com/gomodule/redigo v1.8.2 // indirect

[justinian]

Using go get before ever using the module is one workaround, but since module auto-discovery is broken for this module due to the v2.0.0 tag (and people might go build before realizing this is a problem), I'd recommend the preferred workaround be to tell people to explicitly add the module and version to the go.mod file.

Since you probably can't delete the v2.0.0 tag without breaking projects already pointed at it, perhaps a more long-term fix would be to add a v2.0.1 that does have a go.mod so that auto discovery won't choose 2.x versions without a /v2 in the import path?

[stevenh]

Testing here I didn't need to use go get either e.g.:
```
go mod init github.com/stevenh/redis-test
go: creating new go.mod: module github.com/stevenh/redis-test
vi main.go

Save with content:
```go
package main

import "fmt"

func main() {
        p := redis.Pool{}

        fmt.Println("vim-go", p)
}

go-vim picked up and added redis to imports and go.mod

more go.mod
module github.com/stevenh/redis-test

go 1.14

require github.com/gomodule/redigo v1.8.2

[stevenh]

I believe this has been answered, so going to close. Please do reopen if this is not the case.

o, I got same problem

I have tried go clean -modcache, than use go mod tidy, but still return error: github.com/gomodule/redigo: module github.com/gomodule/redigo@latest found (v2.0.0+incompatible), but does not contain package github.com/gomodule/redigo

By the way, go get github.com/gomodule/redigo/redis@latest was worked before go mod tidy with no error

I also tried github.com/gomodule/redigo v1.8.3 in go.mod, then:

PS F:\work\home\redis-cli> go mod tidy

so, how to fix it??

[stevenh]

I can't reproduce this here, but I have go1.15.5

Have you tried using the latest version of golang in case its a bug in go module support?

Also what does go.mod look like?

[juwell]

try new version of golang? em..., maybe it's worth to try

but when i google this problem at i got this error first time, i found many people have same problem with different version of golang, the way they shared who resolved this problem can't fix my problem. -_-|||

my go.mod is here

module redis-cli

go 1.13

require (
    github.com/go-redis/redis/v8 v8.4.10
    github.com/gomodule/redigo v1.8.3 // indirect
    github.com/spf13/cobra v1.1.1
)

[stevenh]

If it's a bug in the module support of the version you're using update might fix it.

The other thing to try is: go clean (without the -modcache) to see if there is something else stale which is causing bad behaviour

I think it's not a bug in the module, and of course not my code's bug, because I just import redigo without any other code

// main.go

package main

import (
    "fmt"
    _ "github.com/gomodule/redigo"
)

func main() {
    fmt.Println(`hello world`)
}

// go.mod

Your main.go is invalid as the package that gets used is github.com/gomodule/redigo/redis not github.com/gomodule/redigo.

Using your example I also see:

go build
go: finding module for package github.com/gomodule/redigo
main.go:6:2: module github.com/gomodule/redigo@latest found (v1.8.3), but does not contain package github.com/gomodule/redigo

Correcting main.go results in success

package main

import (
        "fmt"

        _ "github.com/gomodule/redigo/redis"
)

func main() {
        fmt.Println(`hello world`)
}

go build
go: finding module for package github.com/gomodule/redigo/redis
go: found github.com/gomodule/redigo/redis in github.com/gomodule/redigo v1.8.3

waow, it's fixed me, thank you~~~ 👍
