goinstall: code.google.com/p/go-tour/pic: cannot download: code.google.com/p/go-tour/pic

I know that there is problem with path setting .. i also checked this post

export PATH=$PATH:/home/sakthi/sakthig/code/my/go/go/bin
export GOROOT=/home/sakthi/sakthig/code/my/go/go
export GOPATH=$GOROOT/bin

This is my current path setting.. any help ?

Answer 1

The Go Tour project has been updated recently.

The Go weekly.2011-11-09 release renamed the json package to encoding/json.

The Go weekly.2011-12-14 release changed the naming for the go-tour package import paths from "go-tour.googlecode.com/hg/tree" to "code.google.com/p/go-tour/tree".

Update to the Go weekly release (Keeping up with releases).

$ cd $GOROOT/src
$ hg pull
$ hg update weekly
$ ./all.bash

Then install the go-tour/tree package.

$ cd $GOROOT
$ goinstall -v -fix code.google.com/p/go-tour/tree
goinstall: open /home/peter/go/goinstall.log: no such file or directory
goinstall: code.google.com/p/go-tour/tree: download
goinstall: cd / && /usr/bin/hg clone https://code.google.com/p/go-tour /home/peter/go/src/pkg/code.google.com/p/go-tour
goinstall: selecting tip
goinstall: cd /home/peter/go/src/pkg/code.google.com/p/go-tour && /usr/bin/hg update
goinstall: code.google.com/p/go-tour/tree: install
goinstall: cd /home/peter/go/src/pkg/code.google.com/p/go-tour/tree && /bin/bash gomake -f- install

Answer 2

$ goinstall go-tour.googlecode.com/hg/gotour
go-tour.googlecode.com/hg/gotour: download failed: unsupported import path;
should be "code.google.com/p/go-tour/gotour"
Run goinstall with -fix to gofix the code. ($GOPATH is not set)
$ goinstall -dashboard=false code.google.com/p/go-tour/gotour
$ (cd ~/go && hg id)
82fdc445f2ff weekly/weekly.2011-12-14
$ 

Answer 3

Specifically in the weekly.2011-12-14, goinstall was updated to reject google paths that don't follow the format: "code.google.com/p/go-tour/tree"

This format would fail: "go-tour.googlecode.com/hg/tree"
