无法使用docker-compose运行容器

在我的ubuntu vbox上执行以下shell时出现错误。

docker-compose up -d

Step 1/4 : FROM postgres:9.4
 ---> d1b08fdd94ed
Step 2/4 : RUN mkdir /docker-entrypoint-initdb.d/census/
 ---> Using cache
 ---> 35c38c9966fb
Step 3/4 : COPY ./sql/census/ /docker-entrypoint-initdb.d/census
ERROR: Service 'db' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder974990962/sql/census: no such file or directory

我在Google上进行了搜索，但没有获得解决此问题的提示。

你能帮我吗？

感谢您的关注。最好的问候，Liki
