准备

安装之前，你需要在你用于开发区块链应用或者操作超级账本的开发机检查是否已经安装好需要的环境。

安装cURL

如果本地没有cURL或者运行cURL报错，你需要安装最新版本的cURL

Docker and Docker Compose

• MacOSX, *nix, or Windows 10: Docker Docker version 17.06.2-ce or greater is required.
  Older versions of Windows: Docker Toolbox - again, Docker version Docker 17.06.2-ce or greater is required.

• Installing Docker for Mac or Windows, or Docker Toolbox will also install Docker Compose.
  If you already had Docker installed, you should check that you have Docker Compose version 1.14.0 or greater installed.
  If not, we recommend that you install a more recent version of Docker.

  #检查版本
  docker --version
  docker-compose --version

Go语言支持

超级账本许多组件都需要Go语言支持

Go version 1.10.x is required.
#环境变量
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

Node.js Runtime and NPM

• Node.js version 9.x is not supported at this time.
