<p>I'm working with python3, and i'm trying to install " <strong>cairocffi</strong>" on Ubuntu.
To do this, i've successfully installed:</p>

<ol>
<li>python-dev</li>
<li>libffi-dev</li>
<li>cffi</li>
</ol>

<p>But when i've trying to install "cairocffi" with <code>pip install cairocffi</code>,I got:</p>
