Python veya PyPy kullanırken,&nbsp;pip ile&nbsp; gevent gibi bir paket kurarken aşağıdaki hatayı alıyorsanız, &ccedil;&ouml;z&uuml;m i&ccedil;in gerekli paketleri apt ile kurmanız gerekmektedir.
&nbsp;
&nbsp;
<blockquote>
ERROR: Could not build wheels for gevent which use PEP 517 and cannot be installed directly
&nbsp;
</blockquote>
&nbsp;
<pre><code class="prettyprint">sudo apt&nbsp;install -yqq gcc make python-dev python3-dev libffi-dev</code></pre>
&nbsp;
Kurulumu tekrar deniyoruz.
<pre><code class="prettyprint">pip3.6 install -U gevent</code></pre>
&nbsp;
&nbsp;
NOT: Ayrıca pip, wheel ve setuptools paketlerini g&uuml;ncellemekte iyi olur.&nbsp;
<pre><code class="prettyprint">pip3.6 install -U wheel setuptools pip</code></pre>
