racer runs fine in terminal, crashes when run from emacs #1128

Closed ravarspath closed 4 years ago

ravarspath commented 4 years ago

I installed racer via cargo +nightly install racer and when I run RUST_BACKTRACE=full CARGO_HOME=/home/ryan/.cargo RUST_SRC_PATH=/home/ryan/Desktop/source/rust/src/ ~/.cargo/bin/racer find-definition 12 9 /home/ryan/Desktop/code/metamorpher/src/main.rs in the terminal

I get

MATCH with_ssl,106,11,/home/ryan/.cargo/registry/src/github.com-1ecc6299db9ec823/mailin-embedded-0.5.0/src/lib.rs,Function,pub fn with_ssl(&mut self, ssl_config: SslConfig) -> Result<&mut Self, Error>
END

and when run from emacs (via eshell).
