Why Am I Getting the \"mysqlclient 1.3.13 or newer is required; you have 0.9.3\" Error in Django?

Django: Troubleshooting "mysqlclient 1.3.13 or newer is required; you have 0.9.3" Error

Installing the mysqlclient module is essential for connecting Django to a MySQL database. However, users may encounter the error "mysqlclient 1.3.13 or newer is required; you have 0.9.3" due to a possible issue with using pymysql instead of mysqlclient.

pymysql vs. mysqlclient

PyMySQL is an older and less reliable MySQL connector compared to mysqlclient. It is typically used due to its ease of installation, as it does not require any system libraries. On the other hand, mysqlclient provides better performance and stability, making it the preferred choice for high-performance applications. Django uses mysqlclient by default for these reasons.

Fixing the Error

To resolve this error, you can follow these troubleshooting methods:

1. Verify PyMySQL Usage:

   • In your Django project, locate the code snippet:

     <code class="python">import pymysql
     pymysql.install_as_MySQLdb()</code>

2. Patch pymysql Version:

   • Modify the code as follows:

     <code class="python">import pymysql
     pymysql.version_info = (1, 3, 13, "final", 0)
     pymysql.install_as_MySQLdb()</code>

   • This will simulate a newer version of pymysql, satisfying the Django dependency.

Additional Considerations

If you require improved performance, it is recommended to switch to mysqlclient. However, installation may require additional steps, such as installing libssl-dev before running:

<code class="python">pip install mysqlclient</code>
