Command for specifically installing dev-dependencies

[mcandre]

• Hard build-time library dependencies like json can be specified as [dependencies], to be installed when cargo build executes.
• Hard built-time dependencies like thrift can be specified as [build-dependencies], to be installed when cargo build executes.
• Test-time dependencies like quickcheck can be specified as [dev-dependencies], to be installed when cargo test executes.

But how about soft build-time dependencies like cargo-script supposed to be managed with Cargo.toml, that are not imported by any Rust code but still required for shell commands?

Could we get a cargo subcommand or flag to forcibly install all [dev-dependencies], regardless of whether the dependency is referenced by an extern crate or not?

As a workaround, I am currently managing these kinds of development dependencies by manually executing cargo install <dependency>, but I would prefer to manage these with the same Cargo.toml file as everything else.

Has there been any kind of feature added for this since this issue was opened?

This is a little confusing to read as its using terms from other ecosystems (you don't "install" dependencies). I'm assuming what is wanted is the ability to make bin dependencies available. In light of that, it appears to be a duplicate of issues like #5120 and #2267. Closing in favor of those. If there is a reason we should re-evaluate this, let us know!
