Error

The binary is not found because your shell's PATH variable does not include the Cargo bin directory where cargo install places executables. Add the Cargo bin directory to your PATH environment variable and reload your shell configuration.

export PATH="$HOME/.cargo/bin:$PATH"
echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

For Windows PowerShell, run:

$env:Path += ";$env:USERPROFILE\.cargo\bin"
[System.Environment]::SetEnvironmentVariable("Path", $env:Path, "User")

Restart your terminal and verify the installation with rustc --version.

When you install a Rust tool, it is saved in a special folder that your computer doesn't check by default. You need to tell your computer to look in that folder whenever you type a command. It is like adding a new aisle to a grocery store map so the cashier knows where to find the item.
