Seeing this post <a href="https://stackoverflow.com/q/21440230/2544762">Install mysql-python (Windows)</a>.

It points out installing such a pip environment is difficult, needs many other dependencies.

But I finally know that if we use <code>mysqlclient</code> with a version down to <code>1.3.4</code>, it don't need that requirements any more, so try:

<pre><code>pip install mysqlclient==1.3.4

For Python 3+ version

install <code>mysql-connector</code> as:

<pre><code>pip3 install mysql-connector 
</code></pre>

Sample Python DB connection code:

<pre><code>import mysql.connector
db_connection = mysql.connector.connect(
 host="localhost",
 user="root",
 passwd=""
)
print(db_connection)
</code></pre>

Output:

<pre><code>&gt; &lt;mysql.connector.connection.MySQLConnection object at &gt; 0x000002338A4C6B00&gt;
</code></pre>

This means, database is correctly connected.

If your are using SQLAlchemy and the error is in <code>/site-packages/sqlalchemy/dialects/mysql/mysqldb.py</code>:

<pre><code>from ...connectors.mysqldb import (
 MySQLDBExecutionContext,
 MySQLDBCompiler,
 MySQLDBIdentifierPreparer,

</code></pre>

so you may have missed mysqldb connector for <code>SQLAlchemy</code> and the solution is to re-install sqlalchemy after installing <code>mysql-python</code> module.

Faced this issue with mysql.connector.python version 8.0.24 on mac(if code base is same then the issue should happen in windows as well). <a href="https://github.com/mysql/mysql-connector-python/blob/master/lib/mysql/connector/django/base.py" rel="nofollow noreferrer">This file</a> on line 51 imports &quot;from django.db.backends.mysql.base import DatabaseWrapper as MySQLDatabaseWrapper&quot;. The <a href="https://github.com/django/django/blob/main/django/db/backends/mysql/base.py" rel="nofollow noreferrer">imported file</a> has following code 14-20(exact code and error that you received is part of code
<pre><code>try:
 import MySQLdb as Database
except ImportError as err:
 raise ImproperlyConfigured(
 'Error loading MySQLdb module.\n'
 'Did you install mysqlclient?'
 ) from err
</code></pre>
The error is formed here. Not sure why this import keeps coming back in different version of mysql connector but 8.0.23 does not have the import, so I reverted to that version and error was gone... This is incase you wish to continue to work with mysql.connector.python

I am using Python version 2.5.4 and install MySQL version 5.0 and Django. Django is working fine with Python, but not MySQL. I am using it in Windows Vista.
