and I have set up rust to "nightly" using rustup override set nightly still facing the error.

Please advise! Thank you!
It seems like the error is with the maturin command using "Z" option which is only applicable in nightly compiler. you can first try to install
Install nightly toolchain:
Switch to nightly toolchain as default toolchain:
and then try to install those dependencies. Hope this works!!!!
