Hi Maria, servo/media requires the same Rust toolchain as Servo [1]. Servo's build takes care of setting up the toolchain for you, but unfortunately servo/media does not do that yet. So you need to install and set it up manually. You can use rustup [2][3] for that (i.e. rustup install nightly-2019-03-26 && rustup default nightly-2019-03-26).
