This is the downside of using a nightly toolchain. Hopefully, we can move off of that when async/await is stabilized in Rust (should be Q1). A change in the nightly compiler broke the tokio-async-await crate. See tokio-rs/tokio#814.

To fix this locally, add this to the bottom of your Cargo.toml.

[patch.crates-io]
tokio-async-await = { git = "https://github.com/tokio-rs/tokio", rev = "cbecb877971826871fa409364722cf684bf3cabf" }

As soon as tokio-async-await is released at 0.1.5 you should be able to remove this.
