title: Cannot install snips-nlu on Raspberry Pi: Can not find Rust compiler
body: <p>I followed <a href="https://snips-nlu.readthedocs.io/en/latest/installation.html" rel="nofollow noreferrer">these instructions</a> to install snips-nlu on a Raspberry Pi:</p>
  
  <ol>
  <li>Rust Installation: <code>curl https://sh.rustup.rs -sSf | sh</code></li>
  <li>Setuptools-rust:   <code>sudo python3 -m pip install setuptools-rust</code></li>
  <li>NLU Installation:  <code>sudo python3 -m pip install snips-nlu</code></li>
  </ol>
  
  <p>My console log:</p>
  
  <pre class="lang-none prettyprint-override"><code>Building wheels for collected packages: snips-nlu-utils, snips-nlu-parsers
  .
  .
  .  error: Can not find Rust compiler
  </code></pre>
  
  <p>I tried with different Python versions.</p>
  
  <p>I found <a href="https://github.com/PyO3/setuptools-rust" rel="nofollow noreferrer">setuptools-rust</a>, but it did not help, because I don't understand what I should do with it.</p>
  
  <p>How can I fix this Rust compiler error message and install snips-nlu on a Raspberry Pi?</p>
