dev-dependencies of dependencies specified by path are not found

[wfraser]

Example

root/Cargo.toml:

...

[dependencies]
path-dependency = { path = "path-dependency" }

root/path-dependency/Cargo.toml:

...

[dev-dependencies]
env_logger = "*"

Running cargo outdated -v gives:

error: Direct dependency env_logger not found for package path-dependency

It only seems to do this if the dependency is specified by path; regular crates.io dependencies don't have this problem.

Possibly the same problem with git patched dependencies via [patch.crates-io].

This error only appears when the inner crate is not a workspace member of the outer one, i.e. adding this to root/Cargo.toml:

[workspace]
members = ["path-dependency"]

makes the error go away.
