    volumes:
      - ${APP_PATH_HOST}: ${APP_PATH_CONTAINER}

(和Dockerfile)

RUN docker-php-ext-install 
     pdo_mysql 
     && a2enmod
     rewrite

But after I try to run

(但是在我尝试跑步之后)

docker-compose up --build

I have the problem

(我有问题)

ERROR: The Compose file '.docker-compose.yml' is invalid because:
services.web.working_dir contains an invalid type, it should be a string
services.composer.volumes contains an invalid type, it should be a string
services.web.volumes contains an invalid type, it should be a string
services.db.volumes contains an invalid type, it should be a string

I tried to change docker-compose file version to 2 - does not work I tried to use '' and "" the same problem.

(我试图将docker-compose文件版本更改为2-不起作用，我尝试使用“和”相同的问题。)

I want to run my server successfully.

(我想成功运行服务器。)
