Code no longer builds due to broken URL github.com/russross/blackfriday/v2

[jinzishuai]

We use packages that uses blackfriday and today we got

github.com/russross/blackfriday (download)
[13:54:28]package github.com/russross/blackfriday/v2: cannot find package "github.com/russross/blackfriday/v2" in any of:
[13:54:28]	/opt/go/src/github.com/russross/blackfriday/v2 (from $GOROOT)
[13:54:28]	/opt/TeamCity/buildAgent/work/34f7a3c3b5ec8423/server/syntropy3/src/go/src/github.com/russross/blackfriday/v2 (from $GOPATH)

I checked that the URL of github.com/russross/blackfriday/v2 is not valid.

Anything changed recently? Our daily builds have been working for quite a long time.

Thanks Shi

What version of Go are you using?

[jinzishuai]

We are using go version go1.9.2 linux/amd64. thanks

[moorereason]

It’s related to Go modules. You need at least 1.9.7. See https://github.com/golang/go/wiki/Modules.

@moorereason I have Go 1.11. So what gives?

import "gopkg.in/russross/blackfriday.v2"

$ go build
go: downloading gopkg.in/russross/blackfriday.v2 v2.0.1
build fancypackage: cannot find module for path gopkg.in/russross/blackfriday.v2

[moorereason]

@wizardist, not sure, but it's unrelated to this issue.

[wizardist]

@moorereason yeah, maybe a bug in go mod, maybe smelly package cache, but import "github.com/russross/blackfriday/v2" worked.

I am experience this problem too when doing Travis CI, on local everything OK. Any update on this?

I had this problem with skaffold importing "gopkg.in/russross/blackfriday.v2" My workaround is to use a replace directive in my go.mod:

replace gopkg.in/russross/blackfriday.v2 => github.com/russross/blackfriday/v2 v2.0.1

@bttk

replace gopkg.in/russross/blackfriday.v2 => github.com/russross/blackfriday/v2 v2.0.1

Thank you! You just made my day! I've spent hours because of this:

go: gopkg.in/russross/[email protected]: go.mod has non-....v2 module path "github.com/russross/blackfriday/v2" at revision v2.0.1
go get: error loading module requirements

Now go build works without complains. – Just out of curiosity: What made you think of that workaround?

[bttk]

@mwat56 I saw the same error

At first I thought it was an error in the module path, but go docs say it is an exception for paths in gopkg.in

I saw, that replace can be used to override version and location, so I used it.

[tbarbugli]

@bttk I am having a similar issue, what was your remediation?

[mwat56]

@tbarbugli

I am having a similar issue, what was your remediation?

In go.mod this:

require (
    // …
    gopkg.in/russross/blackfriday.v2 v2.0.1
)

replace gopkg.in/russross/blackfriday.v2 => github.com/russross/blackfriday/v2 v2.0.1

Hope it helps.

when i use this `require ( // … gopkg.in/russross/blackfriday.v2 v2.0.1 )

replace gopkg.in/russross/blackfriday.v2 => github.com/russross/blackfriday/v2 v2.0.1`

i got this message go: github.com/russross/blackfriday/[email protected] used for two different module paths (github.com/russross/blackfriday/v2 and gopkg.in/russross/blackfriday.v2) anything wrong?

[...] i got this message go: github.com/russross/blackfriday/[email protected] used for two different module paths (github.com/russross/blackfriday/v2 and gopkg.in/russross/blackfriday.v2) anything wrong?

Did you check your source files to make sure your imports point to gopkg.in/russross/blackfriday.v2?

yes , first I imports "gopkg.in/russross/blackfriday.v2" and it shows me the error above , later i change all (imports and module in go.mod) to "github.com/russross/blackfriday/v2" , it worked

I'm on go version go1.15.6 windows/amd64. Indeed, running go get github.com/russross/blackfriday/v2 did not work and caused the following:

cannot find package "github.com/russross/blackfriday/v2" in any of:
        C:\Go\src\github.com\russross\blackfriday\v2 (from $GOROOT)
        C:\Users\Atulya\gopath\src\github.com\russross\blackfriday\v2 (from $GOPATH)

I was able to get it working perfectly fine using: go get gopkg.in/russross/blackfriday.v2 and importing using

import "gopkg.in/russross/blackfriday.v2"

Thanks for developing this! 👍🏼

Same issue here with Go 1.15.11 on linux/amd64 when running go get on a project that has github.com/russross/blackfriday/v2 v2.0.1 in its go.mod requirements (and imports the GitHub name as well). This works as a workaround:

replace github.com/russross/blackfriday/v2 => gopkg.in/russross/blackfriday.v2 v2.0.1

Considering the former is supposed to be the canonical v2 URL though, something is definitely afoul here.
