Building from source missing clap derive macro

[mwly]

When Cloning this Repo and building from source i got
Parser is imported here, but it is only a trait, without a derive macro

Adding the solution from this stackoverflow thread helped

I didn't open a PR because you might very well have a reason not to enable the flag.

Thanks for the information. I'll have a look as soon as possible.

What's your output of rustc --version?

Looks like you used cargo install --path . as documented. I noticed, it uses different crate versions than the one specified in the Cargo.toml, that are used when running cargo build and the crates aren't compatible.

cargo install --locked --path . uses the crates that are in the Cargo.lock and this worked. Or update the dependencies.

I see you figured the solution out on your own. Thanks for letting us know anyways!
