"SSL certificate verify failed" using pip to install packages

pip install --trusted-host pypi.python.org autopep8 (any package name)

This command will add pypi.python.org to the trusted sources and will install all the required package.

I ran into the error myself and typing this command helped me install all the pip packages of python.

As stated here https://bugs.python.org/issue28150 in previous versions of python Apple supplied the OpenSSL packages but does not anymore.

Running the command pip install certifi and then pip install Scrapy fixed it for me
