tour: go tool: no such tool "tour"

[twang2218]

Context: https://tour.golang.org/welcome/3

I tried to run the go tour on my local, however, the command in the tour is not working by default:

$ go tool tour
go tool: no such tool "tour"

There is no tour in the go tool

$ go tool
addr2line
api
asm
cgo
compile
cover
dist
doc
fix
link
nm
objdump
pack
pprof
trace
vet

After I manually go get the package:

go get golang.org/x/tour/gotour

Then, I still not be able run go tool tour, however, I can run gotour directly.

$ gotour

I installed go by brew install go.

Here is my go env:

Just realize there are bunch of related issues have been reported:

• there is no such tool like "tour" #175
• tour: go tool tour does not work #116
• tour: "go tool tour" doesn't seem to work now? #153
• tour: 'go tool tour' doesn't work #170
• tour: Inappropriate detail regarding go tour #228
• tour: Go offline command outdated #132
• tour: local tour instructions incomplete #8

I also tried it on my Ubuntu 16.04, and installed by recommended approach snap:

$ sudo snap install --classic go
go 1.9 from 'mwhudson' installed
$ go version
go version go1.9 linux/amd64
$ go tool tour
go tool: no such tool "tour"

It still not work by default.

If you are running a linux distro(in my case archlinux), be sure to add the go bin i.e. ~/go/bin to your environment variables. In my case, I added it to the ~/.profile file.
