clap derive macro Error Example

Putting this one here for anyone searching for the error message:

error: cannot find derive macro `Parser` in this scope
  --> src/main.rs:10:17
   |
10 | #[derive(Debug, Parser)]
   |                 ^^^^^^
   |
note: `Parser` is imported here, but it is only a trait, without a derive macro
  --> src/main.rs:4:5
   |
4  | use clap::Parser;
   |     ^^^^^^^^^^^^

error: cannot find attribute `clap` in this scope
  --> src/main.rs:13:7
   |
13 |     #[clap(short, long)]
   |       ^^^^
   |
   = note: `clap` is in scope, but it is a crate, not an attribute


The solution for me with this message was to update
my `Cargo.toml`` file from:

Code

clap = 4.3.10"

To:

Code

clap = { version = "4.3.10", features = ["derive"] }
