For more information about this error, try `rustc --explain E0554`.
error: failed to compile `aries-cli v0.1.0`, intermediate artifacts can be found at `/var/folders/tt/l0mq4_tj0vs26brlh1r3b03w0000gn/T/cargo-installi14Ln4`

Caused by:
  could not compile `aries-cli` due to previous error

Since I didn't have the Rust toolbelt installed on my system, it's worth mentioning that I installed it prior to attempting to install the aries-cli by following the official installation guide.

[berendsliedrecht]

Ah the iter_zip (awesome function) is only enabled in nightly versions.

To install nightly:

rustup default nightly

To set nightly:

rustup default nightly

To set back to stable:

rustup default stable

I will add this to the docs or more likely replace the iter_zip with a stable feature.

Thanks for the report :)

[karimStekelenburg]

I think we can solve this by adding a Prerequisites section to the README. This is a good place to explain how to install Rust and the fact that it needs to be nightly :)

[karimStekelenburg]

Verified that the latest version works with the stable version of Rust. I still think that we need to add a prerequisites section to the README, but I'll close this one and add a new issue.
