gvm安装

gvm github地址

1.简介​

gvm是一个go版本管理工具，可以很方便的切换当前系统使用的go的不同版本，以解决在不同开发环境下go版本和api等的依赖关系

2.安装​

:::tip说明

如果系统使用的是 zsh 则需要将 bash 修改为 zsh

mac操作系统要求

xcode-select --install
brew update
brew install mercurial

:::

可以使用官方的一键安装脚本进行安装

bash < <(curl -s -S -L https://raw.githubusercontent.com/moovweb/gvm/master/binscripts/gvm-installer)

脚本内容如下，其中有一行配置 SRC_REPO=${SRC_REPO:-https://github.com/moovweb/gvm.git} ，这里的地址是 github.com ，由于某些特殊原因，我们需要将这个地址修改为加速地址

:::tip说明

修改

​ https://github.com/moovweb/gvm.git

修改为 https://gh.api.99988866.xyz/https://github.com/moovweb/gvm.git

:::

脚本中已经有 EOF 了，因此这里使用 AAA

cat > gvm-install.sh << 'AAA'

手动执行脚本

zsh gvm-install.sh

安装完成后会提示如下，根据提示重启终端或者运行命令即可

Please restart your terminal session or to get started right away run
 `source /Users/pptfz/.gvm/scripts/gvm`

验证安装

$ gvm version
Go Version Manager v1.0.22 installed at /Users/pptfz/.gvm

3.使用​

列出所有已安装的go版本

gvm list

列出所有可供下载的go版本

gvm listall

安装最新版

gvm install go

安装指定版本

gvm install go1.17.7

从二进制安装

gvm install go1.17.7 -B

删除某一个go版本

gvm uninstall go1.19.8

完全删除gvm和所有已安装的go版本和包

gvm implode

完全删除gvm也可以直接删除目录

rm -rf ~/.gvm
