问题
My package install (using PIP & Easyinstall) fails every time when I install PyopenSSL and Scrapy on Python 2.7. OS: Win 8.1 64 Bit.
The error details are below:

Troubleshooting done so far:
1.The error is same with Easyinstall and Pip
2. Changed the logs to Verbose levels.
3.Checked multiple Stackoverflow links, still no luck:

I was having the same issue. Here is what i did:
Install Cryptography first on your computer, using the following link: https://cryptography.io/en/latest/installation/#on-windows
if you don't have openSSL installed on your computer the above page will have the link for that. Add the environment variables as mentioned in the link and try to install it again.
