having the same problem, can anyone help?

[hexfusion]

@yeyongyong @maps could you please test #10337

[maps90]

@hexfusion superb! it works

[MatevzFa]

How can I use this change in my project, while using a go.mod file?

[reefbarman]

I still see this issue using the latest release, I am using go modules in go 1.11 is there anything specific I need to do to resolve this?

[reefbarman]

exact error is here:

panic: codecgen version mismatch: current: 8, need 10. Re-generate file: C:/Go/pkg/mod/github.com/coreos/[email protected]+incompatible/client/keys.generated.go

goroutine 1 [running]:

When can we expect a release which contains the fix to get cut?

@reefbarman you can vendor in the dependency at the fix's merge commit to pick up the changes.

[lifangmoler]

Seeing the same issue using the latest version

[lifangmoler]

is the latest version containing the fix for this?

[lifangmoler]

@mnajork-palantir how to do vendor in the dependency at the fix's merge commit to pick up the changes.?

[mnajork-palantir]

@lifangmoler what are you using as your dependency management tool?

Here's the commit containing the fix: https://github.com/etcd-io/etcd/commit/f3fbedc88f52527ef4dd051bea53e8c99a569831

[lifangmoler]

@mnajork-palantir I am using go mod. I can see the commit and the change. but still not sure how to pick the change

[lifangmoler]

trying this go get github.com/coreos/etcd@f3fbedc, seeing new errrors: go: finding github.com/coreos/etcd f3fbedc go: github.com/coreos/[email protected]: parsing go.mod: unexpected module path "go.etcd.io/etcd" go: error loading module requirements

[hexfusion]

Played with this a little and I found if you are using go mod for your project and running into issues with "codecgen version mismatch: current: 8, need 10. Re-generate file:" try:

go get github.com/ugorji/[email protected] which is the version we pin https://github.com/etcd-io/etcd/blob/master/go.mod#L45

go.mod

module github.com/hexfusion/stuffz

require (
             github.com/coreos/etcd v3.3.12+incompatible
[snip]
             github.com/ugorji/go v1.1.1 // indirect
)

Curious if this helps folks.

[hexfusion]

@lifangmoler @mnajork-palantir @reefbarman ^

[reefbarman]

@hexfusion so I have gotten further with the suggestion change but then received this

..\Go\pkg\mod\github.com\coreos\[email protected]+incompatible\client\keys.generated.go:15:2: unknown import path "github.com/ugorji/go/codec": ambiguous import: found github.com/ugorji/go/codec in multiple modules:
        github.com/ugorji/go v1.1.1 (C:\Gamedev\Go\pkg\mod\github.com\ugorji\[email protected]\codec)
        github.com/ugorji/go/codec v0.0.0-20181204163529-d75b2dcb6bc8 (C:\Gamedev\Go\pkg\mod\github.com\ugorji\go\[email protected])

Will dig to see if I can resolve this but I am not specifically requiring github.com/ugorji/go/codec

[reefbarman]

okay I found it was github.com/spf13/viper also requiring go/codec and I forked this and updated it to use the same versions of etcd and go/codec and it built. But ideally etcd would support go mod so things can be versioned correctly

EDIT: Spoke too soon including the forked viper in another project then caused it to fail again with the above issue and this time I can't find the dependency that is importing github.com/ugorji/go/codec, so unable to resolve the issue

[lifangmoler]

@hexfusion It is working for me after i tried go get github.com/ugorji/[email protected]. thanks

[antgubarev]

Still have same problem

[hexfusion]

@amarox make sure to bump etcd we updated to a go mod friendly version of ugorji/go recently https://github.com/etcd-io/etcd/pull/10481

[antgubarev]

github.com/coreos/etcd v3.3.12

[timestee]

Still have same problem

github.com/coreos/etcd v3.3.12+incompatible // indirect
github.com/ugorji/go v1.1.1 // indirect

Facing the same issue,

panic: codecgen version mismatch: current: 8, need 10. Re-generate file: /Users/sakib/go/pkg/mod/github.com/coreos/[email protected]+incompatible/client/keys.generated.go

goroutine 1 [running]:

        /Users/sakib/go/pkg/mod/github.com/coreos/[email protected]+incompatible/client/keys.generated.go:45 +0x135

[radekg]

Same problem, this appears to be okay:

[[constraint]]
  name = "github.com/etcd-io/etcd"
  revision = "1adc28822343e2f14cc5e493a663fba1adf54186"

[alee792]

Bcmills' solution resolved this for me.

go get github.com/ugorji/go/codec@none

[lucasalcantara]

this solution worked for me.
I just did GO111MODULE=on go get -u github.com/ugorji/[email protected] and worked beautifully.
