golang 1.10 报错的解决办法：

go tool asm: exit status 2
flag provided but not defined: -V

runtime/internal/sys

flag provided but not defined: -std

解决： ubuntu 系统：
export GOROOT=/usr/lib/go

CentOS 系统：
export GOROOT=/usr/lib/golang

不同版本覆盖混用会导致如下报错：

解决办法：删除部署路径的golang，全新部署

snippet

int64 to String

import "strconv"
strconv.FormatInt(int64Value, 10)

string to int64

import "strconv"
int64Value, err := strconv.ParseInt(strValue, 10, 64)
    if err != nil {
        log.Fatal(err)
    }
