Setting up rust jupyter notebook

I am trying to install the experimental rust jupyter-notebook kernel with these two options on Mac M1: cargo install --locked evcxr_jupyter, cargo install evcxr_jupyter but I'm getting the following errors:

error: could not compile evcxr_jupyter (bin "evcxr_jupyter") due to 1 previous error

error: failed to compile evcxr_jupyter v0.21.1, intermediate artifacts can be found at /Users/bett/cargo-target.

To reuse those artifacts with a future compilation, set the environment variable CARGO_TARGET_DIR to that path.

What's the "previous error"?
