这是docker-compose.yml
version: “2”
services:
web:
build: .
environment:
MONGO_URI="mongodb://ravimongo:27017"
ports:
— “3000:3000”
links:
— ravimongo
depends_on:
— ravimongo
ravimongo:
image: mongo:3.2.6
ports:
— “27017:27017”
这是错误：
ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version ("2.0","2.1","3.0") and place your service definitions under the `services` key,or omit the `version` key and place your service definitions at the root of the file to use version 1.

我在http://www.yamllint.com/和https://codebeautify.org/yaml-validator中验证了yaml语法.我无法找到问题.
最佳答案
YAML有效.但是,您使用左双引号“如此：
版本：“2”
根据错误,似乎Docker Compose无法正确解析版本.如果你使用的是left double quotation mark而不是quotation mark,那么Docker编写的版本将是“2”而不是2,因此它不能将它等同于支持的版本(“2.0”,“2.1 “,”3.0“).我建议将其更改为以下内容：
版本：“2”
如果错误仍然存在,请告诉我.
