How Do I Install a Specific Version of a Python Package Using pip?

Installing a Specific Package Version with Python's pip

Problem:

When attempting to install a specific version of a package (in this case, MySQL_python 1.2.2) using pip, the latest version (1.2.3) is installed despite using the == syntax.

Answer:

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

Using --force-reinstall (Recommended):

TL;DR:

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

Details:

  • --force-reinstall: Reinstall all packages, even if they are up-to-date.
  • -v: Verbose mode for additional output.

Using -I --ignore-installed:

TL;DR:

pip install -Iv "MySQL_python==1.2.2"

Details:

  • -I: Ignores existing installed packages and overwrites them.
  • -v: Verbose mode for additional output.

Additional Notes:

  • For MySQL_python 1.2.2, it may be necessary to manually download and install the package as the PyPI download link is broken.
  • Uninstall any existing versions of the package before installing the specific version to avoid conflicts.
