Hi everyone!
Context: I'm using a PowerPC cluster without access to the Internet and without any admin permissions. I have to build the tokenizers library, which depends on PyO3. Rust is already built-in in the system I'm using, but PyO3 requires a nightly version of Rust. So, I have downloaded the right Rust version and I'm planning to use the corresponding binaries.
The problem is that when I call cargo, it still uses the non-nightly version of Rust, apparently. I have specified the required rustc path by setting the $RUSTC environment variable, but it appears to be completely ignoring this variable.
Any hint? I don't have any previous experience with Rust.
Many thanks in advance.
