Use CURL to download get-pip.py:
curl --http1.1 https://bootstrap.pypa.io/get-pip.py --output get-pip.py
Execute the downloaded Python file
python get-pip.py
Then add C:\Python37\Scripts
path to your environment variable. It assumes that there is a Python37
folder in your C drive. That folder name may vary according to the installed Python version
Now you can install Python packages by running
pip install awesome_package_name
