|

</div>
|

<p>As most operation systems are coming with Python3 installed by default. So it is
|
||
time for searx to support Python3. But don’t worry support of Python2.7 won’t be
|
||
dropped.</p>

|

<p>Please make sure that you run at least Python 3.5.</p>
|
||
<p>To run searx, first a Python3 virtualenv should be created. After entering the
|
||
virtualenv, dependencies must be installed. Then run searx with python3 instead
|
||
of the usual python command.</p>
