Pip uninstall Scrapy with all its dependencies
pip uninstall currently doesn't support removing the dependencies. You can manually go to the folder where scrapy is installed and delete it. For example: /usr/local/lib/python2.7/dist-packages/scrapy. 
For example if it is at '/PATH/TO/SCRAPY', run this command on the terminal: 
sudo rm -rf /PATH/TO/SCRAPY
I had installed Scrapy with pip install scrapy. It also install all its requirement packages Installing collected packages: zope.interface, Twisted, six, cssselect, w3lib, parsel, pycparser, cffi, pyasn1, idna, cryptography, pyOpenSSL, attrs, pyasn1-modules, service-identity, queuelib, PyDispatcher, scrapy. So, is it possible to uninstall scrapy and all its requirement packages with a terminal command?
