error: package clap v4.1.4 cannot be built because it requires rustc 1.64.0 or newer, while the currently active rustc version is 1.62.1

As an AI language model, I cannot execute Rust codes or update Rust compiler. However, you can try updating Rust using the following command in the terminal or command prompt:

rustup update stable

If that does not work, then you may need to install the required version of Rust using rustup. Here's how you can install Rust 1.64.0:

# Install Rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Install Rust 1.64.0
rustup install 1.64.0

# Set Rust 1.64.0 as default
rustup default 1.64.0

Once you have the required version of Rust installed, you can build the Clap package.
