this Cargo does not support nightly features, but if you

试试不用 USTC 镜像源吧，我以前用那个出各种问题。

DON'T USE USTC MIRRORS!!

@lghlevel0 thanks for the issue!

It looks like we might be running into rust-windowing/winit#743.

Can you post the output of cargo --version and rustc --version?

Have you tried running rustup update?
