How to Install a Specific Older Version of MySQL-Python (e.g., 1.2.2) using pip?

Installing a Specific Version of MySQL-Python with pip

You want to install version 1.2.2 of MySQL-Python in a fresh virtual environment created with the --no-site-packages option. However, PyPI only provides version 1.2.3.

Solution:

To install the older version, use the following command:

pip install --force-reinstall -v MySQL_python==1.2.2

Explanation:

• --force-reinstall: Reinstalls all packages, even if up-to-date.
• -v: Provides verbose output (optionally -vv or -vvv for more verbosity).

Alternative Solution (Outdated):

pip install -Iv MySQL_python==1.2.2

• -I: Ignores installed packages and overwrites them.
• -v: Provides verbose output.

Note:

Using -I may cause issues with installations managed by other package managers or different versions of the package. See the Python documentation for more information on this caveat.

Additional Step:

Since the PyPI URL for MySQL-Python 1.2.2 no longer works, you may need to install it manually:

pip uninstall MySQL_python
pip install -Iv http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz/download
