Can't build fresh nickel project

[Christoph Burgdorf]

It seems there's something broken with nickel right now.

I wanted to start a fresh project basically to create repro steps for an issue with rust-mustache that I reported a while back. But when I try to set up a fresh nickel project I get.

I get this even if all my main.rs has is:

#[macro_use]
extern crate nickel;

use nickel::*

fn main() {
}

I just ran into this as well.
I tried rustc:
nightly-2015-08-15
nightly-2015-09-01

both failed with the same error.

[MarkSwanson]

Solution:

• edit Cargo.toml so the nickel dependency info is:

[dependencies.nickel]
git = "https://github.com/nickel-org/nickel.rs.git"
features = ["unstable"]

Note: I'm using a nightly version of Rust. You probably don't have to if you comment out the features.

Ah, damn it. Thanks @MarkSwanson, I forgot that I switched to nightly a couple of days ago. This bug doesn't exist when compiled with stable rust. I'm closing this for now then.
