pip install cryptography -> error...failed with exit status 1120

Question

I am trying to install the cryptography module for python yet I keep getting errors and so far I have been able to solve each one as they come including:

1. error: Unable to find vcvarsall.bat
2. mysql-python install problem using virtualenv, windows, pip
3. Installing lxml for Python 3.4 on Windows x 86 (32 bit) with Visual Studio C++ 2010 Express
4. Failing to run pip install cryptography on Windows 7

However I have ran into an error that no matter how hard I look I find nothing so I decided I shall do what everyone else has done in the past and ask.

What do I need to do to get the error: command 'C:\\Program Files (x86)\\Microsoft\\Visual Studio\\14.0\\VC\\BIN\\amd64\\link.exe' failed with exit status 1120 error to go away so I can install the cryptographic module.

P.S. Yes I have tried easy_install

Answer 1

I got the same error message: link.exe failed with exit code 1120 while installing pycocotools. I installed all tools from desktop development with c++ and restarted my powershell and the error resolved by itself
