我对其中一项服务的 Dockerfile 进行了一些更新，但这些更改在运行时没有反映出来docker-compose build，甚至在使用--no-cache选项时也没有反映出来。
我在运行之前添加了两个两个参数pip install -f requirements.txt，但它们不会在任何时候执行：它直接进入需求步骤。
$ docker-compose build --no-cache
mongo uses an image, skipping
postgres uses an image, skipping

我正在使用 docker-compose 1.21.2 和 Ubuntu 18.04.2。
我如何保证docker-compose没有使用旧版本的 Dockerfile，即使我描述的是我想要执行构建，没有任何缓存（--no-cache）？
