Can't install rpolars from source

Just trying to get a dev setup for this and following the directions I get:

Yeah many run into this error when compiling polars. I will try to make readme more precise on this.

See e.g.
pola-rs/polars#4273
And...
https://rust-lang.github.io/rustup/concepts/channels.html

Try installing and set to nightly

rustup toolchain install nightly
rustup default nightly

and then run rextendr::document() again

rpolars is migrating to pola-rs

You're welcome to reopen the issue here if relevant here or join the pola-rs discord channel for casual discussions.

Many Thanks
