On a windows 7 machine I have pip version 1.5.6 installed:
pip 1.5.6 from C:\Users\dietz\PNC\tas\ENV\lib\site-packages (python 2.7) In order to find the reason for an error I want to install a different version of pip, which worked fine for me. So how can I uninstall pip and install version 1.2.1 instead?

Two Steps to Install Specific Version of a Package with Pip: 1) Install virtualenv and create an environment. 2) Install the Specific Version you Need with Pip.
Use a Virtual Environment to Downgrade Python on Windows To create a virtual environment, we can use the command pip install virtualenv on the command prompt. We need to download the required version from the official website. After this, we need to execute virtualenv \pathof\the\env -p \pathof\the\python_install.exe .
Open a command or terminal window (depending on the operating system) cd into the project directory. pip uninstall <packagename>
pip itself is just a normal python package. Thus you can install pip with pip.
Of cource, you don't want to affect the system's pip, install it inside a virtualenv.
pip install pip==1.2.1 If downgrading from pip version 10 because of PyCharm manage.py or other python errors:
python -m pip install pip==9.0.1 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
