go-tour: when suggesting users "go offline", give full instructions about go-tour

[GoogleCodeExporter]

You need to set up a workspace (GOPATH) into which the tour will be installed. 
See this doc: http://golang.org/doc/code.html

Ah, hey, thanks. So, read the recommended page. Set GOPATH=/usr/local/go,
then tried the "go get" again and got the same permission denied. used
"sudo" to mkdir the place, and then permission denied for wherever /p/ so
used sudo again for that one, then got this:

# cd .; hg clone -U https://code.google.com/p/go-tour /usr/local/go/src/pkg/
code.google.com/p/go-tour

(check hostfingerprints or web.cacerts config setting)
abort: Permission denied: /usr/local/go/src/pkg/code.google.com/p/go-tour
package code.google.com/p/go-tour/gotour: exit status 255

Don't set GOPATH to /usr/local/go

Make a directory in your home directory, like 'gocode', and set it to that

  GOPATH=$HOME/gocode

The overarching problem is that you can't write to /usr/local/go as a regular 
user. That's fine. GOPATH specifies a place you can write to, and that's where 
the tour should be installed to.

Thanks, A..., for the personal attention! So unexpected. I have lots of
programming experience, not so much Linux.

Your general advice seems right, but it did not work:

$ echo $HOME
/Users/iangcoville
$ GOPATH=$HOME/gocode
$ go get code.google.com/p/go-tour/gotour
# cd .; hg clone -U https://code.google.com/p/go-tour /usr/local/go/src/pkg/
code.google.com/p/go-tour
warning: code.google.com certificate with fingerprint
8e:ab:3a:93:45:99:6b:95:07:71:7a:c2:1f:68:90:af:78:a9:3c:9a not verified
(check hostfingerprints or web.cacerts config setting)
abort: Permission denied: /usr/local/go/src/pkg/code.google.com/p/go-tour
package code.google.com/p/go-tour/gotour: exit status 255

However, my brother, who is also a programmer, AND a Linux expert,
suggested "sudo chown -R iangcoville /usr/local/go" and then the go get,
and that DID WORK.

After reading your "How to program..." then looking at those error
messages, I have to wonder why it seems to violate the very first rule of
packages, that there be src, pkg, and bin at the *same level* (usr/local/go/
*src/pkg*/code.google.com/p/go-tour)?

Yours,
Ian

So anyway, now that the gotour is installed, I drilled down to  
/usr/local/go/src/pkg/code.google.com/p/go-tour/gotour and found two files: 
goplay.go and local.go. Running goplay.go gave me an "are you crazy?" -type 
message, local.go gave me a date and time and an invitation to browse to 
127.0.0.1:3999 which I did and there it is, the tutorial!

However, when I try to RUN anything, I get a red letter warning "Error 
communicating with remote server". What gives?

Do you see anything in the console (where you ran gotour) when this happens?

Nope. Still the invitation to "browse 127.0.0.1" etc.

I was having the exact problems described here, but this worked for me:

Everyone should read at least http://golang.org/doc/code.html#GOPATH
