Examples don't compile anymore due to conflicting deps?

[darthdeus]

I'm not sure if this is a problem on my side, though the examples I've tried all seem to fail because two versions of nix are in use, e.g. when I run this on main

cargo run --example complex_game_loop_lua --features lua54

I get the following error

$ cargo run --example complex_game_loop_lua --features lua54                main@781754a

Hi there! thanks for using bevy_mod_scripting!

I've had a quick look, this is a weird error, it appears that this might be coming from upstream in Bevy:

• https://github.com/bevyengine/bevy/issues/6353
• https://github.com/diwic/alsa-rs/issues/90

Could you try the recommended temporary fix?: https://github.com/diwic/alsa-rs/issues/90#issuecomment-1288134557

[est31]

Oh no it's also affecting the cpal 0.13 branch... have to file a fix for that too...

[makspll]

I am assuming this was the issue, please re-open if this didn't solve your problem
