# Install Python and prepare virtualenv for Invoke tasks' dependencies.

# Install latest stable Rust via rustup.
# This is necessary because we're running on OSX as language:generic
# (due to Python hack above), so we don't have Rust handy.
brew install rust
rustc --version
cargo --version
# TODO: use rustup and test on multiple Rust versions;
# this would likely make it necessary to move the installation to before_script:,
# as per: https://docs.travis-ci.com/user/installing-dependencies/#Installing-Projects-from-Source
