# The Specified Version Was Not Installed with Pipenv

<p>In the Pipfile,</p>
<pre><span>[packages]<br />...<br />Werkzeug </span>= <span>"&lt;1.0.0"</span></pre>
<p><span>is specified, but when I run</span></p>
<pre>pipenv install <span>--</span>system <span>--</span>skip-lock <span>--</span>dev <span>--</span>deploy</pre>
<p><span>version 1.0.1 gets installed.</span></p>
<p></p>
<p>In the case of --dev, I needed to specify the version of Werkzeug in dev-packages.</p>
<pre>[<span>dev-packages</span>]<br /><span mce-data-marked="1">...<br /></span><span>Werkzeug </span>= <span>"&lt;1.0.0"</span></pre>
<p></p>
