# 1.1.1 Go编译器安装

安装Go多版本管理器（推荐）

Linux/macOS下自动安装Go多版本管理器（适用于 bash、zsh）

$ curl -sSL https://raw.githubusercontent.com/voidint/g/master/install.sh | bash
$ cat << 'EOF' >> ~/.bashrc
# 可选。检查g别名是否被占用
if [[ -n $(alias g 2>/dev/null) ]]; then
    unalias g
fi
EOF 
$ source "$HOME/.g/env"

# 1.1.2 工具链安装

安装protobuf编译器（使用场景：开发mesh微服务、使用protobuf作为与客户端通信的协议）
- Linux, using apt or apt-get, for example:
```
$ apt install -y protobuf-compiler
$ protoc --version  # Ensure compiler version is 3+
```

# 1.1.3 Docker环境安装

安装docker

进入docker (opens new window)官网下载最新版docker (opens new window)安装包安装

安装docker-compose

Linux

$ sudo curl -L "https://github.com/docker/compose/releases/download/v2.36.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose

MacOS，docker desktop (opens new window)中已内置docker-compose，故无须单独安装
Windows, download from Github (opens new window):

安装开发组件

$ cd ./docker
$ docker-compose up -d
