How to Force Pip to Install a Specific Version of MySQL_python?

Installing MySQL_python with a Specific Version Using Pip

In an attempt to install version 1.2.2 of MySQL_python in a virtualenv with the --no-site-packages option, you may encounter difficulties. Despite providing pip with the specific version argument, it still installs version 1.2.3.

Solution

To install a specific package version with pip, you can use the following options:

• --force-reinstall -v: This option is recommended as of 2022-12-28. It forces the reinstallation of packages, even if they are already up-to-date, and provides verbose output.

Alternative Option

• -Iv: This option (introduced in the original answer) also works by ignoring installed packages and overwriting them, while providing verbose output.

Example

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

# or

pip install -Iv "MySQL_python==1.2.2"

Additional Considerations

• Ensure you have uninstalled any existing MySQL_python package before installing the specific version.
• If the PyPI URL for the desired version is not working, you can download the package source directly from the package's source repository using the -I option, followed by the download URL. For MySQL_python version 1.2.2, you can use the following command:

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