docker - Rocket Chat docker-compose.yml 未验证 - 错误：在文件“./docker-compose.yml”中，服务必须是映射，而不是 NoneType

Question

当我尝试运行docker-compose up -d 时出现错误。我不知道（我不熟悉 YAML）

我收到此错误错误：在文件“./docker-compose.yml”中，服务必须是映射，而不是 NoneType

我正在使用以下脚本，我尝试的网址是https://rocket.chat/docs/installation/paas-deployments/aws/#set-up-docker-containers

 version: '2'

 services:
 rocketchat:
     image: rocket.chat:latest
