The easiest way: first, install rust and cargo, either through your distribution, or thorough rustup if your distribution doesn't have it yet. Then run "cargo install -f ripgrep". It'll download the source code, build, and install to ~/.cargo/bin, which rustup adds to $PATH for you by default.

Edit: the "-f" in the "cargo install" command is for updating; without the -f, it refuses to install over an already installed version. The first time you install, you can omit the -f.

Note that if you install Rust through Debian, it likely won't be new enough to compile the latest version of ripgrep. I believe Debian packages Rust 1.14, and the last version of ripgrep to work on Rust 1.14 was 0.5.2. So, `cargo install --vers 0.5.2 ripgrep` might be what you want on Debian.

Debian stable has 1.14, but Debian testing has 1.22.1.
