failed to select version for parity-scale-codec when building

[Guillaume Heu]

simply running cargo build --release -p data-avail gives me the following dependency version error for the crate parity-scale-codec :

error: failed to run custom build command for `da-runtime v6.0.0 (/home/user/avail/runtime)`

I haven't seen that exact error before. You might be on an older version of rustc based on your error messaging:

Using rustc version: rustc 1.59.0-nightly (8f117a77d 2021-12-13)

Could you try updating to the current version? To verify, I ran the following commands on a new Ubuntu VM, and it worked as expected:

git clone https://github.com/maticnetwork/avail.git
cd avail
curl https://sh.rustup.rs -sSf | sh -s -- -y
source "$HOME/.cargo/env"
rustup toolchain install nightly
rustup default nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
cargo build --release -p data-avail

Some example output at the end of the process:

That worked, thank you.
