Good everyone, I am installing magic mirror, I would like to install spotify and for that I need the librespot library, librespot needs rust to work, but I always get the error "No such file or directory (os error 2) ". I've searched the forum but I haven't seen anything. I don't understand much either, I'm a newbie. OS: Raspbian 11 32bits.

[package]
name = "librespot"
version = "0.4.2"
authors = ["Librespot Org"]
license = "MIT"
description = "An open source client library for Spotify, with support for Spotify Connect"
keywords = ["spotify"]
repository = "https://github.com/librespot-org/librespot"
readme = "README.md"
edition = "2018"
[workspace]
[lib]
name = "librespot"
path = "src/lib.rs"
error: command failed: 'cargo': No such file or directory (os error 2)
Command (no matter the command, they all fail):
cargo build --release
cargo install librespot
              
Yes, I have the "cargo" folder with the executable, it is also added in the PATH.
pruden@raspberrypi:~/.cargo $ echo $PATH
/home/pruden/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
pruden@raspberrypi:~ $ ls .cargo/bin/
cargo         cargo-miri     rust-analyzer  rustfmt      rust-lldb
cargo-clippy  clippy-driver  rustc          rust-gdb     rustup
cargo-fmt     rls            rustdoc        rust-gdbgui
              
When I do an update I also get this error:
pruden@raspberrypi:~ $ rustup update
info: syncing channel updates for 'stable-aarch64-unknown-linux-gnu'
info: checking for self-update
  stable-aarch64-unknown-linux-gnu unchanged - ***(error reading rustc version)***
info: cleaning up downloads & tmp directories
              
Hmm, maybe you have a second version of Rust installed from a package of your OS? What does it say when your run:
> whereis rustup
> whereis rustc
> whereis cargo
              
pruden@raspberrypi:~ $ whereis rustup
rustup: /home/pruden/.cargo/bin/rustup
pruden@raspberrypi:~ $ whereis rustc
rustc: /home/pruden/.cargo/bin/rustc
pruden@raspberrypi:~ $ whereis cargo
cargo: /usr/share/cargo /home/pruden/.cargo/bin/cargo
              
pruden@raspberrypi:~ $ ls /usr/share/cargo/registry/*

Weird. I don't know where this is coming from but it looks fishy to me. I'm a little bit out of my depth here and I don't want to recommend just deleting it and breaking something on your machine 
Maybe if your run ~/.cargo/bin/cargo build --release, it will work?
              
Same mistake... I am so confused...
pruden@raspberrypi:~ $ .cargo/bin/cargo build --release
error: command failed: 'cargo': No such file or directory (os error 2)
              
The other reason you can get “No such file or directory” for an executable that clearly exists is when the error is for a dynamically linked library instead. Cargo doesn’t have any unusual dependencies, but you could try
ldd .cargo/bin/cargo
and see if it's successful or not.
              
pruden@raspberrypi:~ $ ldd .cargo/bin/cargo
	/usr/lib/arm-linux-gnueabihf/libarmmem-${PLATFORM}.so => /usr/lib/arm-linux-gnueabihf/libarmmem-v8l.so (0xf7170000)

	/lib/ld-linux-armhf.so.3 (0xf794a000)
              
I notice you said you’re using 32-bit Raspbian, but the rustup output you included says
info: syncing channel updates for 'stable-aarch64-unknown-linux-gnu'
which is obviously for 64-bit ARM. I would expect this to be either arm-unknown-linux-gnueabihf or armv7-unknown-linux-gnueabihf. I don’t know about the error message, but this can’t be helping.
I believe the commands to install a different toolchain for ARM would be:
rustup toolchain install stable-arm-unknown-linux-gnueabihf
rustup default stable-arm-unknown-linux-gnueabihf
              
That was the problem, I was using the wrong version, I don't understand why I was downloading that version, now everything works correctly.
Thank you all for the help!  ^-^
