how do i downgrade a package using pip?

If you need to downgrade a package using pip, it is relatively simple to do so. While pip is the most popular package manager for Python package installation, there are other options available as well. In this article we will explain the steps to perform a downgrade on a package using pip.

1. Identify the package name and version:

The first step before downgrading any version of a Python package is to identify which specific version of the package you need to downgrade. To do this, use the pip search command to find the available versions of that particular package in the PyPI repository. For example, if we wanted to downgrade version 3.2 of 'PyQt5', we would run the command: `pip search PyQt5`. This would list all available versions from which you can pick and choose what best fits your project needs .

2. Uninstall your current version:

Once you know what specific version of a python package you want to downgrade, you must first uninstall your current version of this particular package using `pip uninstall`. For example if we wanted to uninstall our currently installed 'PyQt5' package we would enter the command: `pip uninstall PyQt5`.

3. Install your desired version:

Finally, once you've uninstalled your current version of this particular python program, you are ready to install your desired version – at this point, just issue `pip install` with version specified as argument. For example if we wanted to install our previously identified "PyQt5-3.2" then we should enter the command : `pip install PyQt5==3.2`. This will install the desired older version specified while bypassing those that come afterward which could be incompatible with our projects needs and requirements.
