Blockchain 致命错误：运行时：安装geth时内存不足

我想知道安装geth对机器的要求是什么。或者在安装geth时出错？

我不知道如何安装，但要在mainnet上运行它，至少需要3到4 Gb的ram。

# make geth
build/env.sh go run build/ci.go install ./cmd/geth
>>>/usr/lib/golang/bin/go install -ldflags -X main.gitCommit=   -v
github.com/ethereum/go-ethereum/dashboard
#  github.com/ethereum/go-ethereum/dashboard
fatal error: runtime: out of memory

runtime stack:
util.go:45: exit status 2
exit status 1
make: ***[geth] Error 1
