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:

cryptography recommends using pip. Make sure you install the wheel package, use a recent pip, and probably use --no-cache-dir and --only-binary – paul trmbrth
Thanks for your response Paul, I am trying Pip install <Package Name>, in this case : PyopenSSL & scapy. – Suraj_j
Use pip install --no-cache-dir --only-binary cryptography (it will install PyOpenSSL dependency), and then pip install scrapy – paul trmbrth
Thanks Paul.. This is what worked in my case pip install --only-binary :all cryptography and then pip install scrapy. – Suraj_j
Your timely response is highly appreciated. – Suraj_j

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.
