I cannot reproduce the issue, rustc --version works fine on my aarch64 device.

Title and error message mentions rustup. Are you running rustc or some (non-termux-compiled) rustup?

Did you ever tried to use rustup? It is not going to work as Rust officially doesn't provide rustc binaries compatible with Android OS. -- Termux isn't standard distribution: https://wiki.termux.com/wiki/Differences_from_Linux

Check your PATH and your home directory to ensure that no rustup parts hijacking Termux rustc executable, remove all parts of rustup.

On Termux Rust compiler can be installed only using pkg install rust.

If you need some std components, look what is available by running pkg search rust or pkg search rust-std.

I get the same problem. I install it using pkg install rust and it seems to be all fine. But then it complains there's no default set. Nothing I've tried had worked (like setting environment variables or creating a config.toml file in .cargo/bin to point to the libraries that are installed).

[tmak2002]

I have reinstalled Termux since then it works.

[Shoresh613]

Did that the day before I got the message. So didn't work for me apparently, but maybe could try again..

This was exactly it for me.

I got this issue (even though it was working previously) and when I saw this comment it reminded me that I had tried to use rustup at one point. I checked my $PATH variable and found that the first path in the variable was /data/data/com.termux/files/home/.cargo/bin, once I removed that rustc commands worked without issue. 👍
