Can't run cargo nexus run when following the steps in docs

[qdriven]

I just follow the steps in docs extractly, but can't run the project.
The error is:

The issue is that you don't have support installed for the riscv32i-unknown-none-elf target. This happens quite often when working with custom targets in Rust.

Try this:
rustup target add riscv32i-unknown-none-elf

And if it still doesn't work, check your configuration.

Still doesn't work. I try to figure it out. Thank you.

@qdriven This may be related to issues with rustup and brew installations of Rust conflicting, see the discussion here: #293

Closing due to lack of activity.
