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

System Info

  • Windows 7 Home Premium - Service Pack 1 - 64-bit - AMD64x

This is probably way out-of-date information, but just in case… I notice that your Visual Studio is in Program Files (x86), not Program Files. Microsoft at least used to distribute free 32-bit-only versions of Visual Studio, which couldn't be used for building 64-bit apps because they were missing the 64-bit SDK. Do they still do that? Because not having the MSVCRT from the 64-bit SDK would explain why the linker can't find things like sscanf… – Fraser
You are likely missing a library and/or it's development sources so the linker is failing to link the C-extensions in cryptography. – Mas
There are pre-built cryptography wheels -- Install one of those so you don't have to build it. – Mas
@abarnert, it's a 64-bit compiler: C:\Program Files (x86)\Microsoft\Visual Studio\14.0\VC\BIN\amd64\cl.exe. Visual Studio installs all compilers under %ProgramFiles(x86)%. The OP's OpenSSL libs clearly are not built using Visual Studio 2015 (14.0). The new VC++ is a major update and reorganization of the Windows C runtime, so OpenSSL will have to be built from source. – Irishman
Wheels installed correctly, I have the 64-bit compiler like @eryksun said. Could it be that I am using a prerelease version of python? What other things should I try? – Vaios
pip installs wheels out of the box. The wheel package is for building wheels, so you can build a package once and deploy to multiple development environments, but you still need to be able to build the package. If you can't build OpenSSL from source, you'll need to use Python 3.4 and either the pre-built 3.4 wheel that can be pip installed from PyPI, or build your own version using Visual Studio 2010 or the Windows SDK 7.1. – Irishman
downgrading to python 3.4.3 made it work – Vaios

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
