Describe the Bug

I was following the example code athttps://rustwasm.github.io/docs/book/game-of-life/setup.html.

I was able to installcargo install cargo-generate without a problem, and also have the latest LTS version of NPM. (Also, did arustup update this morning to update my stable installation of rustc and cargo.)

However, when I runcargo generate --git https://www.github.com/rustwasm/wasm-pack-template and name my projectwasm-game-of-life, it fails to clone with the error⛔ Git Error: failed to clone into: /Users/andrewlee/Documents/Projects/Personal/Rust/wasm-game-of-life4g21l6

Steps to Reproduce

1. cargo install cargo-generate
2. cargo generate --git https://www.github.com/rustwasm/wasm-pack-template
3. Name project

If applicable, add a link to a test case (as a zip file or link to a repository we can clone).

Expected Behavior

Not sure but I assume it should have set up a nice webasm project for me.

Actual Behavior

⛔ Git Error: failed to clone into: /Users/andrewlee/Documents/Projects/Personal/Rust/wasm-game-of-life4g21l6

If applicable, add screenshots to help explain your problem.
