What did you do?

go run main.go

What did you expect to see?

Run successfully. The issue may be caused be China not able download golang.org/x/net through normal go get. So I try git clone it from github.com/golang/net and put in my pkg/cache/download folder, but still not work.

In normal none mod enviroment, usually we resolve this kind of issue by my above methodology.

Any tip to resolve this issue if the mod auto get not work? Aka, any manual tip?

What did you see instead?

build github.com/ScottHuangZL/blockchain: cannot find module for path golang.org/x/net/trace

Duplicate of #28652. Please use a replace statement or other solutions which are pointed in that thread.

Thanks.

[ScottHuangZL]

Why close this issue? And #28652 seem also not resolved.

I try add replace golang.org/x/net/trace v0.0.0-20181129055619-fae4c4e3ad76 => github.com/golang/net/trace v0.0.0-20181129055619-fae4c4e3ad76 //indirect

also not work.

Let me restate issue again:

1. I am plan import "github.com/dgraph-io/badger"
2. It indirect require golang.org/x/net/trace
3. I know need try use replace methodology to resolve this kind of issue
4. But still not work with below pain points:
   a. I have to try find out the version. Can we let it blank or use * to mean match any version?
   b. Even I try go to github to capture your latest commit and put in mod file, it still not work.
   c. I try git clone github.com/golang/net and put in cache folder, also useless.

Any better and easy way? Or else, I have to abandon mod way and go back to traditional way again.

I closed this because it is the duplicate of #28652. Closing this does not mean that the issue is fixed. It just means that the issue is being tracked somewhere else.

You have rightly commented on your pain points on that issue. We will be tracking those in that thread.

Thanks.

I try below, and finally work!
go mod edit -require=golang.org/x/net@v0.0.0
go mod edit -replace=golang.org/x/net@v0.0.0=github.com/golang/net@latest
But the "go build" take a long time to complete build. ==> I have concern for the long build time even it finally success complete, how to resolve it?? Thanks.

If I try "go build -x -v", it will be failed with below message:
Fetching https://golang.org/x/net?go-get=1
https fetch failed: Get https://golang.org/x/net?go-get=1: dial tcp 216.239.37.1:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

It means every build actually it try fetch from online again for x/net. Why? thanks.

A quick way:
go mod tidy
go mod vendor
go build -mod=vendor

Then the build speed still fast!!!
