Docker compose not building because of an error that has been removed

问题

When I use the command docker-compose up in the directory that has the Docker compose Dockerfile, I am hit with the error below. The error was that in acp times app there was an extra brace, which I removed. When I try to run the container again I get the same error message, why is this?

I am new to docker, if any additional info is needed to help solve the problem let me know, I'm not even sure what I am looking for, I followed the docker docks simple instructions. Could it be that something else in my python code is incorrect?

Like @avigil said you need to rebuild your image in order to update it.

If you want to do it in one command you can type:

docker-compose up --build

If you really want to be sure that your containers are recreated run the following command:

docker-compose up --build --force-recreate
