use and import cli.yml file to finish project-1 failed

[PhzCode]

General Question

The sourse in github using clap crate is coding in the kvs.rs file. However, I use the cli.yml to do it, and I can not pass some test cases.

cli.yml file

name: project-1
version: "1.0"
author: *
about: get some args to do something
args:
    - INPUT:
        help: the flag to input
        required: true
        index: 1
    - V:
        short: V
        multiple: false
        help: show the version
subcommands:
    - set:
        about: to set the key-value with the input
        version: "1.0"
        author: *
        args:
            - key:
                index: 1
                help: the key is needed.
                required: true
            - value:
                index: 2
                help: the value is needed.
                required: true
    - get:
        about: to get the value by the key
        version: "1.0"
        author: *
        args:
            - key:
                index: 1
                help: the key is needed.
                required: true
    - rm:
        about: to remove the key-value by the key
        version: "1.0"
        author: *
        args:
            - key:
                index: 1
                help: the key is needed.
                required: true

    }

    match matches.subcommand() {
        ("set", Some(_matches)) => {
            eprintln!("unimplemented");
            exit(1);
        }
        ("get", Some(_matches)) => {
