System information

$bash>> make build/env.sh go get -v ./... build/env.sh: 32: exec: go: not found make: *** [Makefile:10: all] Error 127

=====env.sh missing===== once I fixed that issue comes:

#make build/env.sh go get -v ./... go get: no install location for directory /room/ethash-mining-pool/build/_workspace/src/github.com/techievee/ethash-mining-pool outside GOPATH For more details see: 'go help gopath' make: *** [Makefile:10: all] Error 1

path exists and ~ethash-mining-pool is link to the root "ethash-mining-pool" /build.
