My case: I had to install Apache cassandra. I already had Python3 installed in my D: drive. With loads of development work in process on Python 3, i didn't wanted to mess my Python 3 installation. And, i needed Python2 only for Apache cassandra.

You came here looking for answer, so:

<ul>
<li>I assume you have all prequisites installed for Apache cassandra, except Python2.</li>
<li>You did not installed Python2 because you already have Python3 up &amp; running on your system.</li>
<li>You are getting error when you are trying to run <code>cqlsh</code></li>
<li>You don't want to install Python2 because you don't want to mess up anything in/on already installed Python3. </li>
</ul>

Well i had same issues. Now, check my answer below.

<a href="https://stackoverflow.com/a/58285774/1513779">https://stackoverflow.com/a/58285774/1513779</a>

Advice:

<ol>
<li>Don't try <code>except ImportError as e:</code> in cqlsh.py as suggested above. You will be caught in loop of numerous errors &amp; warnings. Just install Python2, following steps mentioned in link.</li>
</ol>

In case you have different versions of python I suggest this:

<ul>
<li>Install cqlsh using

python2.7 -m pip install cqlsh</li>
</ul>

This will install cqlsh in the context of your Python2.7 

<ul>
<li>Also you might need to install cassandra-driver as well the same way:

python2.7 -m pip install cassandra-driver</li>
</ul>

You can install python2 alongside with python3, and change the cqlsh.bat file in bin folder from python to python2 like this
<pre><code>@echo off

python2 -V &gt;nul 2&gt;&amp;1

python2 &quot;%~dp0\cqlsh.py&quot; %*

Better to hard code PATH in the batch/shell file 'cqlsh'. Or change the directory to the Python2 installed directory, like I did in the below code.

cd C:\Python27

The reason is because your Cassandra is referencing Python 3 installed on your system. To fix this, do the following..,
<blockquote>
<ol>
<li>Install python 2 on your system.</li>
<li>Add python2 to your environment variables.</li>
<li>Navigate to your Cassandra bin folder eg <code>C:\Cassandra\apache-cassandra-3.11.9\bin&gt;</code></li>
<li><code>py -2 -V</code> (verify that you have python 2 installed)</li>
<li><code>py -2 -m cqlsh</code> (from your Cassandra bin folder.)</li>
</ol>
