Rust, rand gen_range wants 1 arg, not 2?

I am following along the learn rust book from the rust lang website and random number generation is not working.

Specifically, when trying to create a random range like so:

use rand::Rng;

fn main() {
    let s: u32 = rand::thread_rng().gen_range(1, 101);
    println!("{}", s);
}

I get the error:

    Checking learn-rust v0.1.0 (.../learn-rust)
error[E0061]: this function takes 1 argument but 2 arguments were supplied

error: aborting due to previous error

For more information about this error, try `rustc --explain E0061`.
error: could not compile `learn-rust`

To learn more, run the command again with --verbose.

In the rust playground I get the same error?

The version of rand on both local and playground is 0.8.0.
