go version go1.12.9 darwin/amd64
When I installed the golang.org/x/tour project, I ran the comman tour and got an error:
Couldn't find tour files: could not find go-tour content; check $GOROOT and $GOPATH
Here is my go env:
GOARCH="amd64"
GOBIN=""
GOCACHE="/Users/elk/Library/Caches/go-build"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"

GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/5d/q9dj2fxx4t71w0g5g00cvlkh0000gn/T/go-build144784202=/tmp/go-build -gno-record-gcc-switches -fno-common"
I add two lines in .zshrc ：
export GOPATH="$HOME/ccode/go"
export PATH="$PATH:$GOPATH/bin"
The command go get golang.org/x/tour was running with no error.
The strange thing is: echo $GOROOT will display a blank line And echo $GOPATH is consistent with go env.
