Can't compile Source

[deltreey]

I ran into this originally on Linux, but I'm able to reproduce the same error on my Windows machine. I found this when I noticed my own code stopped compiling and erroring on the Rocket dependency. I don't need to use my code to do it though. I can clone rocket and run the hello world example right inside the cloned directory:

C:\git\Rocket\examples\hello_world>cargo --version
cargo 1.46.0-nightly (c26576f9a 2020-06-23)

C:\git\Rocket\examples\hello_world>cargo run --verbose
warning: C:\git\Rocket\contrib\lib\Cargo.toml: Found `debug_assertions` in `target.'cfg(...)'.dependencies`. This value is not supported for selecting dependencies and will not work as expected.

Am I missing something? This feels like it should work. In the example above I'm on Win10, but it gives the same error compiling in a docker container for the rust nightly, or even on my ubuntu 20.04 server.
