What steps will reproduce the problem? 1. type go get code.google.com/p/go-tour/gotour 2. 3.

What is the expected output? What do you see instead?

Nothing happens. I'd expect to build and subsequently be able to run the gotour executable.

What version of the product are you using? On what operating system?

$ go version go version go1.0.2

installed via homebrew on mac os x lion

Please provide any additional information below.

I also tried setting the GOPATH, which didn't seem to change anything.

$ mkdir ~/.golib

$ GOPATH=~/.golib

$ export GOPATH

$ echo $GOPATH /Users/gerad/.golib

$ go get code.google.com/p/go-tour/gotour

$

It doesn't say anything but that doesn't mean it's not doing anything.

Look inside the $GOPATH/bin directory.

nothing is there

$ ls -al ~/.golib/ total 0 drwxr-xr-x 2 gerad staff 68 Jul 13 06:36 . drwxr-xr-x+ 73 gerad staff 2482 Jul 13 10:53 ..

What about the /usr/local/go/bin directory?

yes, there is something there...

$ ls -al /usr/local/Cellar/go/1.0.2/bin/gotour -rwxr-xr-x 1 gerad staff 5358856 Jul 13 06:30 /usr/local/Cellar/go/1.0.2/bin/gotour

running it seems to work

Thanks very much for your help debugging. I'm embarrassed by the user error.

It might make sense to have some output somewhere explaining what is going on with go get. As an example, npm install outputs what files and directories are being created.

Also, I installed go via brew install go so this might be an issue with the homebrew install script, but it looks pretty vanilla: https://github.com/mxcl/homebrew/blob/475cf029382e3236af362a23dfd5c76d18cc31a0/Library/Formula/go.rb

Finally, before any of this happened, I was expecting things to be installed relative to my current directory, and was surprised to see the GOPATH stuff mentioned in other issues. If that bit's always necessary shouldn't it be in the one-liner install instructions?

Anyway, I'm excited to actually get to play with go now. Thanks again for your help.

another user came on irc today saying 'go get doesn't do anything'. turns out they followed the install instructions on slide 2 and downloaded a binary install. the next step is 'go get', but that assumes mercurial, which the user didn't have.

possible solutions: change the install link to point to http://golang.org/doc/install/source or provide a tarball/zip archive of the go tour and document that.

cheers!

I just wanted to point out there there are still issues with doing a 'go get code.google.com/p/go-tour/gotour'. I tried following the instructions on http://tour.golang.org/#3. At first, it came back with not recognizing 'hg' as a command. Surprising, but not a big deal.

Then once hg was in my path, I tried again with the go get, and got the below. As you can see, I'm running the AMD 64 bit 1.0.3 build and it's on Windows 7 64 bit. Anyway, I guess I'll stick with the online version for now, but just thought someone would like to know about this.

Vince, you most certainly have GOROOT set incorrectly. It defaults to /usr/local/go. If you put your Go installation somewhere else, GOROOT should be set to that path.

Run "go env" to see what the go tool thinks your GOROOT is.

Since this bit me, I'll add what helped me out. For those using Homebrew to install Go, you'll find that go env has GOROOT="/usr/local/Cellar/go/1.0.3". Given that, I simply ran brew unlink go && brew link go and then gotour was available on my regular PATH
