I followed these instructions to install snips-nlu on a Raspberry Pi:
- Rust Installation: 
curl https://sh.rustup.rs -sSf | sh - Setuptools-rust:   
sudo python3 -m pip install setuptools-rust - NLU Installation:  
sudo python3 -m pip install snips-nlu 
My console log:
Building wheels for collected packages: snips-nlu-utils, snips-nlu-parsers
.
.
.  error: Can not find Rust compiler
I tried with different Python versions.
I found setuptools-rust, but it did not help, because I don't understand what I should do with it.
How can I fix this Rust compiler error message and install snips-nlu on a Raspberry Pi?
