Rust does not work after install on Raspberry Pi Zero 2 W

[benplay2]

I installed rust on my new Raspberry Pi Zero 2 W (with latest Raspbian version). I ran the following, and got a message in the end that it succeeded:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

After rebooting and running rustc --version, I get a bunch of messages and an error:

To install, run `rustup component add rustc`

rustc --version --verbose:

See error above!

Is there something I'm missing or a setting to change?

Thank you,
Ben

It looks like your rustup install is broken. Probably because it ran out of memory while installing or was otherwise interrupted. You should try reinstalling (run rustup self uninstall), but set RUSTUP_IO_THREADS=1 the whole time.

Awesome, that fixed it! Thank you for the prompt response.

To document what I ran to help others in the future:

export RUSTUP_IO_THREADS=1
rustup self uninstall
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

[pyprism]

export RUSTUP_IO_THREADS=1

Thanks, this works for me. I have a SBC with only 512 mb ram !
