Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

go version go1.10 windows/amd64 go:2018-02-20.1
(Downloaded today)

Does this issue reproduce with the latest release?

Yes

What did you do?

vgo mod -sync after initializing the go.mod

With a simple HelloWorld program:

package main

import (
	"fmt"

	"github.com/graph-gophers/graphql-go/gqltesting"
)

func main() {
    fmt.Println("hello world")
}

What did you expect to see?

Successfully downloading dependencies

What did you see instead?

Moreover I simplified the issue with a HelloWorld program with just 1 import, but that's the same in my real project with more dependencies (the ones not described below are working well):

go: import "github.com/graph-gophers/graphql-go": cannot find module providing package github.com/graph-gophers/graphql-go                                      ge github.com/dgrijalva/jwt-go

I tracked down the issue with for e.g. invalid file name. It's related to windows and zip file handling.

https://github.com/golang/vgo/blob/cc75ec08d5ecfc4072bcefc2c696d1c30af692b9/vendor/cmd/go/internal/modfetch/unzip.go#L57-L66

On systems with PathSeperator equals to / everything works. But on windows the call filepath.Clean replaces slashes with backslashes. This results in filepath.Clean(zf.Name) != zf.Name as the zip package returns the path with forward slashes.

I've build a quick workaround, but I'm not sure if this is a good solution. Maybe @rsc who introduced this lines within a4111b184cac70ec5478914d3b98168dd34bcf4a could tell us more.

name := strings.Replace(zf.Name, "/", string(os.PathSeparator), -1)
if filepath.Clean(zf.Name) != name || strings.HasPrefix(zf.Name[len(prefix)+1:], "/") {
	return fmt.Errorf("unzip %v: invalid file name %s", zipfile, zf.Name)
}

Fixed in golang.org/cl/123580, sorry about the trouble.
(Note that this has not come back into the vgo repo yet but it will around the time we issue beta2.)

@rsc just to be curious, any approximate release date for this beta2?

Thanks for your work 😃

I'm still seeing this in go1.11beta2.

Steps to reproduce (using docker container to isolate..)

docker run --rm -it ubuntu:16.04 bash

Then inside the container:

## Install Deps
apt update; apt install -y curl git

## Install go
cd /tmp
curl -O https://dl.google.com/go/go1.11beta2.linux-amd64.tar.gz
tar xf go1.11beta2.linux-amd64.tar.gz -C /opt/

## Setup go
export GO_ROOT=/opt/go
export GO_PATH=$HOME/go
export PATH=${GO_ROOT}/bin:${PATH}
go version
### go version go1.11beta2 linux/amd64

## Create new fake project
cd
mkdir my-project
cd my-project

# Initialize
go mod -module github.com/example/my-project -init

# Add some code
echo 'package main
import "golang.org/x/text/message"
func main() {
    p := message.NewPrinter(message.MatchLanguage("en"))
    p.Println(123456.78) 
}
' > hello.go

# sync
go mod -sync

Output:

go: finding golang.org/x/text/message latest
go: finding golang.org/x/text v0.3.0
go: import "github.com/example/my-project" ->
	import "golang.org/x/text/message": cannot find module providing package golang.org/x/text/message

Thanks,
Lance

I am guessing due to git version 2.7 which is there in 16.04. The fix for that is in latest master. Either try with master or wait for an RC to get out.

@lancerushing

Didn't get a chance to try master, but I was able to fix it by upgrading git from 2.7.4 to 2.18.0

On the same container:

apt-get install software-properties-common
add-apt-repository ppa:git-core/ppa
apt update
apt upgrade git

Thank you again.

is the fix available in 1.11.2? if not in which release would this be available?
Until it is released, what is the workaround for this issue?

Note that your git version still needs to be greater than 1.7.2. If it is, then this is most probably a different issue. Please open a new bug with the exact steps to reproduce your issue. Thank you.

@agnivade yes the git version is 2.16.1.windows.4.
I can open a new defect for this. But, the error still is the same, do we want to open a new defect or reopen this issue and track it here?
