build failed

[nnovikov]

I tried to build it, but this error happened.

  error: unknown proxy name: 'rustfmt'; valid proxy names are 'rustc', 'rustdoc', 'cargo', 'rust-lldb', 'rust-gdb', 'rls', 'cargo-clippy', 'clippy-driver', 'cargo-miri'
  thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Generate("Failed to generate skeleton for /tmp/.tmpHkN52W/exitstat.o: Broken pipe (os error 32)")', below/build.rs:19:47

Do you have rustfmt installed?

[nnovikov]

Yep.

$ rustfmt --version
rustfmt 1.4.37-stable (c8dfcfe 2021-09-06)

[danobi]

I couldn't repro the error on master. How did you install rust? What kind of build are you doing (cargo install, cargo build from repo, etc.)? Any repro steps?

[nnovikov]

I tried both, cargo install and cargo build --release from repo. Rust installed via curl ... https://sh.rustup.rs | sh on Debian buster and bullseye.

Running into the same issue on debian.

Output from RUST_BACKTRACE=full cargo build --release:
