Cannot install snips-nlu on Raspberry Pi: Can not find Rust compiler

Question

I followed these instructions to install snips-nlu on a Raspberry Pi:

1. Rust Installation: curl https://sh.rustup.rs -sSf | sh
2. Setuptools-rust: sudo python3 -m pip install setuptools-rust
3. 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?

Answer 1

After install Rust compiler:

curl https://sh.rustup.rs -sSf | sh

You can try a restart and then continue the installation of NLU. Restart is to ensure that path of Rust is being recorded in PATH.
