This happens with both yay -S vivid and cargo install vivid .

Are you using Rust 1.30.1 from the repos?

[sharkdp]

I have recently updated vivid to Rust 2018 (>= Rust 1.31) in 099ff6b but completely forgot to update the README and .travis.yml (which currently shows a build failure, too), sorry about that. I'll update this soon.

Does having Rust 1.31 as a dependency cause any problems with packaging for Arch?

[polyzen]

Turns out our Rust maintainer is currently in the process of building the 1.31 package. \o/

[sharkdp]

Ah, great!

If there is any problem, it's also easy to restore 1.30 compatibility.

@kazuf3 The latest vivid release should still work with 1.30.

[kazuf3]

Thank you, I will try.

community/rust is 1.29, btw. I think in this case, do I have to first install rust-nightly-bin first?

[kazuf3]

ah, rustup
I will try it now :)

[kazuf3]

oh, got Rust 1.31 via rustup (and removed repo's rust already). It now works.

Thank you, @polyzen , @sharkdp !!
