问题
I am trying to install PyCrypto 2.6 Library on my computer. But I keep getting the following error
D:\Software\Python\package\pycrypto-2.6>python setup.py build
running build
running build_py
running build_ext
warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.
building 'Crypto.Random.OSRNG.winrandom' extension
error: Unable to find vcvarsall.bat
My System has Windows 8 Pro 64-bit, Visual Studio Enterprise 2012 and Python 3.3
To fix the error I tried to set the Environment Variable VS90COMNTOOLS=%VS110COMNTOOLS% as advised by fmuecke in the post error: Unable to find vcvarsall.bat but it didn't work for me.
Can any one please advise me how to fix this error.
FYI, I don't to install VC2008 etc..
回答1:
I managed to install PyCrypto 2.6 by using the prebuilt binary for Python3.3 from The Voidspace Python Modules.
It doesn't actually fix the error: Unable to find vcvarsall.bat for other package which don't have a prebuilt binaries available.
However it eliminates the need to build PyCrypto package, allowing me to install PyCrypto on my system without getting the error.

I know this is an old question, but I also need today much time to get paramiko wokring. I want to use Python 3.4 and on voidspace, there are no prebuild binaries for 3.4.
Finally, I got a wokring pycrypto by installing "Microsoft Studio Express 2010 C++" and run from the pycrypto 2.7 folder:
python setup.py build --compiler msvc
python setup.py install
python setup.py bdist_wininst
All the "tricks" with enviroment variables doesn't work for me.

For Python 3.5 you can do this:
Install a PyCrypto binary from this site : https://github.com/sfbahr/PyCrypto-Wheels
The best way to do it, is:
64bits Python
c:\Python35\Scripts\pip.exe install --use-wheel --no-index --find-links=https://github.com/sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win_amd64.whl pycrypto
32bits Python
c:\Python35\Scripts\pip.exe install --use-wheel --no-index --find-links=https://github.com/sfbahr/PyCrypto-Wheels/raw/master/pycrypto-2.6.1-cp35-none-win32.whl pycrypto
Of course replace c:\Python35\Scripts\pip.exe by your python pip path
To know your python version, run python and look at the architecture displayed between brackets:
C:\Users\utilisateur>python Python 3.5.1 |Anaconda 4.0.0 (64-bit)| (default, Feb 16 2016, 09:49:46) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.
Hope this can help.

You may install mingw64 and then run from the PyCrypto unzipped files directory:
python setup.py build --compiler=mingw32

I am using Windows 10 - All I needed to do was update my system with Visual C++ Build Tools 2015 which I found on this page: https://blogs.msdn.microsoft.com/pythonengineering/2016/04/11/unable-to-find-vcvarsall-bat/
About mid-page, you will see some download options - choose your python version and download the correct package
I then re-imported the program I was trying to install and NO more error! Woohoo!

if you are VS 2010
SET VS90COMNTOOLS=%VS100COMNTOOLS%
VS 2012
SET VS90COMNTOOLS=%VS110COMNTOOLS%
VS 2013
SET VS90COMNTOOLS=%VS120COMNTOOLS%
and then python setup.py install
