Thanks, this should be fixed by #1097

Hi @kngwyu, I tried again on OS X and I'm still getting the same issue:

@alexanderjamesking : this is fixed by building with nightly as stated in the README.md: cargo +nightly build --release

@alexanderjamesking It looks the problem of a compiler version. Please try rustup toolchain add nightly-2020-03-26 --force and cargo +nightly-2020-03-26 or wait for the upstream update.

That worked, thank you! I'm fairly new to all of this, but racer is working in emacs now 🎉

On Arch, using the Mar 26 nightly compiler, still failing with "no feature negative_impl".
