Description

I run main.go in the example directory and it seems good.

But when I move main.go to another location. It's not good and it seems I import the wrong packages.

Most appear is go-libp2p-core.

$ go run main.go

Try with a copy of go-ipfs/go.{mod,sum}, also don't forget to change the module in the new go.mod to your package name.

[abserari]

you're right! I just copy gomod and gosum but not change the module name.

[abserari]

Oops, I change the module name and not good.

I copy them, and copy main.go to a new directory, but also has this problem.

[Jorropo]

do you still have the same problem ?

[jonnycrunch]

Using go modules you need to require a specific commit as a dependency in the go.mod file i.e.

require(
    github.com/ipfs/go-ipfs v0.4.22-0.20191119151441-b8ec598d5801
)

and it's appropriate hash-link digest in go.sum:

github.com/ipfs/go-ipfs v0.4.22-0.20191119151441-b8ec598d5801 h1:XIYmA2bobIuP+cDk7bSZAXvdDidKlNfQEL/xCH+giSg=
github.com/ipfs/go-ipfs v0.4.22-0.20191119151441-b8ec598d5801/go.mod h1:fld7uJBHEH9mUMtbFZ5CQCVZpkQiwjIt2xuAyrNrPqE=

Latest release (v0.4.22) is out of date for this cutting edge feature. Likely fixed in 0.4.23 release 🤞.

I just remember what I did, just a go init my_package && go mod tidy.

[abserari]

I just remember what I did, just a go init my_package && go mod tidy.

@Jorropo I tried this, but the same problem.
@jonnycrunch yes, I replace github.com/ipfs/go-ipfs to github.com/ipfs/go-ipfs v0.4.22-0.20191119151441-b8ec598d5801 . things gonna be Ok.
