gvm是go的多版本管理工具。

安装

由于网络问题，部分国外网站无法访问：https://raw.githubusercontent.com https://github.com

安装依赖软件

yum -y install gcc bison

安装gvm

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)
如果以上命令没用，浏览器访问 https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer 获取脚本粘贴到server 再执行。
脚本内容：

cat gvm_installer 
#!/usr/bin/env bash

display_error() {
    tput sgr0
    tput setaf 1
    echo "ERROR: $1"
    tput sgr0
    exit 1
}

update_profile() {
    [ -f "$1" ] || return 1

    grep -F "$source_line" "$1" > /dev/null 2>&1
    if [ $? -ne 0 ]; then
            echo -e "\n$source_line" >> "$1"
    fi
}

            else
                    echo "No existing Go versions detected"

脚本执行后会发现

修改本地hosts，绕开dns

vim /etc/hosts
192.30.253.118  gist.github.com
192.30.253.112  github.com
219.76.4.4  github-cloud.s3.amazonaws.com

bash gvm_installer
source /root/.gvm/scripts/gvm 
gvm #该命令有了

然后删除新加的hosts域名解析

装某个版本的go

 gvm install go1.13 -B -s=https://dl.google.com/go/go1.13.4.linux-amd64.tar.gz
 gvm list

安装google/wire

gvm use go1.13
export GOPROXY=https://goproxy.cn
export GO111MODULE="on"
go get github.com/google/wire/cmd/wire
