Doesn't compile out of the box on mac

[FabriceCastel]

When I set the project up with the latest stable Rust release and cargo run it, I get 27 errors from lexical-core-0.4.6, it's various flavors of this:

error[E0308]: mismatched types

    |
    = help: the trait `BitAnd<u32>` is not implemented for `usize`

Seems related to rust-lang/rust#81654, which leads me to believe this could be fixed with a dependency update. I'm relatively new to Rust so I haven't been able to fix it locally yet.

I just ran into the same issue, thanks for posting this and pointing at the Rust issue. I'm also new to Rust and couldn't figure out how to override the lexical transitive dependency. I then just ran cargo update in the project folder, and it updated lexical-core to 0.4.8, which seems to compile just fine:

$ cargo update
...
Updating lexical v2.2.2 -> v2.2.4
Updating lexical-core v0.4.6 -> v0.4.8
...

I actually ran into this issue on Windows as well. The above solution worked.

This also worked for me on macOS Big Sur 11.5.2.

[Xarvalus]

I actually ran into this issue on Windows as well. The above solution worked.

Me too, the issue title maybe should be changed to generic as both Mac & Windows seems to be affected

[alpha2303]

I faced the same issue in Linux as well (Pop OS 21.04). Updating the cargo packages via cargo update helped in compiling successfully.

After cargo update getting this error

Tried the above solution, cargo update, cargo run still fails with this same error.
I don't think i would have to fix it manually, do it?

Any update on this? I'm trying with amethyst = 1.15.1 on OSX.
