go get fails for :github.com/99designs/gqlgen"

Question

I am trying to download "github.com/99designs/gqlgen" package. I want to use it as package rather than module. I just want to start new service in graphql. But when I try to download "github.com/99designs/gqlgen" package, I am getting following error:

go: github.com/russross/blackfriday/v2@v2.0.1 used for two different module paths (github.com/russross/blackfriday/v2 and gopkg.in/russross/blackfriday.v2)

I do have following in my go.mod file replace gopkg.in/russross/blackfriday.v2 => github.com/russross/blackfriday/v2 v2.0.1

Still getting the same error.

Following is go.mod

go 1.14

)

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

Answer 1

There is currently no immediate solution. As noted in the comments, https://github.com/golang/go/issues/26904 notes this problem.

You can try to convince the package users to use the new github.com/russross/blackfriday v2.1.0 . This is the new canonical package path for blackfriday, as noted here .
