        If you are using an outdated pip version, it is possible a prebuilt wheel is available for this package but pip is not able to install from it. Installing from the wheel would avoid the need for a Rust compiler.

        To update pip, run:

            pip install --upgrade pip

        and then retry package installation.

        If you did intend to build this package from source, try installing a Rust compiler from your system package manager and ensure it is on the PATH during installation. Alternatively, rustup (available at https://rustup.rs) is the recommended way to download and update the Rust compiler toolchain.

error: can't find Rust compiler

Have you attempted to install Rust onto your system?

Also cc @messense looks like maturin isn't distributed as a binary for Android?

I don't think you will be able to install Rust through pip, that looks like a completely unrelated package. Try something like this:

https://www.geeksforgeeks.org/how-to-install-rust-on-termux/

[slavikfoxy]

oh, I didn't notice that I wrote pip instead of pkg. Ok, I installed rust but still can't install pydantic. $ pkg install rust rust is already the newest version (1.81.0-1). Summary: Upgrading: 0, Installing: 0, Removing: 0, Not Upgrading: 5

But I couldn't get the rustc version, looks like I won't be able to install it on Termux. https://github.com/termux/termux-packages/issues/12039

[irhamdz]

same issue here

[davidhewitt]

If you cannot get the rustc version then it sounds like this is an upstream Termux issue.

[rfsbraz]

Can confirm the same issue when running my actions: https://github.com/rfsbraz/deleterr/actions/runs/11269028300/job/31336847605

[davidhewitt]

@rfsbraz that looks like a separate issue, you are building for alpine. There's a prebuilt wheel available for that platform so it should be possible to debug why that's not being installed.
