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:
toml
To:
~ fin ~
