Clap maintainer has yanked all the versions up to 2.21.0 which caused this error. The only option (except waiting for the cargo-count author to update dependency) I can see so far — build it manually and put binary to ~/.cargo/bin.

Easy install cargo-count with fix #46:

git clone https://github.com/kbknapp/cargo-count.git
cd cargo-count
git fetch origin pull/46/head:pr-46
git checkout pr-46
cargo install --path ./
# ready!
cargo count --all --unsafe-statistics --exclude target

cargo install --git https://github.com/slerpyyy/cargo-count --branch master works as a one liner.

If you want to install from the original repo (rather than a forked one) with a yanked dependency, and assuming the repo has a Cargo.lock file (which it does in this case), you can use the --locked argument, as so:

cargo install --git https://github.com/kbknapp/cargo-count --branch master --locked
