For some reason image does not compile with rustc 1.15.1. I had the same version of rust and cargo on Windows, CentOS, Ubuntu machines, and image would not compile. Updating Rust resolved the issue.

You can quickly update your Rust by running:
rustup self uninstall && curl https://sh.rustup.rs -sSf | sh
