照着【Nebulas 101 - 01 编译安装星云链】教程，build失败

[haisenling]

在虚拟机ubuntu-18.04里严格按照教程操作，前面均无出现异常，最后一步build失败。信息如下：
lhs@ubuntu:/path/to/workspace/src/github.com/nebulasio/go-nebulas$ sudo make build
cd cmd/neb; go build -ldflags "-X main.version=1.0.1 -X main.commit=a7aaa0aaef2677038562356e1bbdccfb848d2fb4 -X main.branch=master -X main.compileAt=date +%s" -o ../../neb-a7aaa0aaef2677038562356e1bbdccfb848d2fb4
/bin/sh: 1: go: not found
Makefile:66: recipe for target 'build' failed
make: *** [build] Error 127

麻烦帮忙看下是什么原因

go version 和echo $GOPATH可以使用吗

@ChengOrangeJu ，可以的。我不是mac，是Ubuntu
