Docker-compose becomes not to work

I installed docker-compose on CentOS 6.7 with below command line.

# curl -L https://github.com/docker/compose/releases/download/1.5.2/docker-compose-uname -s-uname -m >/usr/bin/docker-compose
# chmod 755 /usr/bin/docker-compose

It works right after installation, but it becomes not to work a few days later.
The message is,

Cannot open self /usr/bin/docker-compose or archive /usr/bin/docker-compose.pkg

What makes this?

Thanks in advance.
