Dgraph安装bug

问题描述
在使用docker-compose up –d命令行启动时出现如下错误：

Traceback (most recent call last):
  File "bin/docker-compose", line 6, in <module>
  File "compose/cli/main.py", line 71, in main
  File "compose/cli/main.py", line 124, in perform_command

TypeError: '<' not supported between instances of 'str' and 'int'

解决方法
日志显示是docker-compose的启动问题，docker-compose.yml中version指的是docker-compose的版本而非dgraph的版本，本人新手将其误以为是dgraph的版本而发生错误

version:"3"
