cargo +nightly install racer returns error | rustc-ap-rustc_data_structures v651.0.0 errors #1101

Lately I have been reading a lot about Rust language and today finally I've decided to give it a try. Unfortunately when I run:

cargo +nightly install racer

I get the following error:

Compiling env_logger v0.7.1

Caused by:

I have alredy ran rustup toolchain add nightly

Is there something I am missing? Any help would be greatly appreciated.

Please try rustup toolchain add nightly-2020-03-30 --force and cargo +nightly-2020-03-30 or wait for the upstream update.

Thanks! I'm running into the same issue and don't want to update to 2020-03-30 because RLS isn't available and I don't use rustup on this machine for multiple installations; the following worked with 2020-03-19 (the last RLS nightly):

cargo install racer \
    --git https://github.com/racer-rust/racer.git \
    --rev ea6f73e4dfc4faafab2f2ac732abf10ce71c80c1
