Caused by:
  build failed

The build appears to be broken due to downstream changes in the atty crate. Looks like softprops/atty#21 is potentially the same cause.

Unfortunately I just found out that this is 100% due to my local Rust installation. Somehow cargo is trying to build for wasm by default, which was causing this issue for me. See softprops/atty#26

Sorry for the noise :/
