I have Python 2.6 and Visual Studio 2008 running on a Win7 x64 machine. When I try to build the basic python extension example in c "example_nt" as found in the python 2.6 sources distribution, it fails:
python setup.py build
And this results in:
running build running build_ext building 'aspell' extension Traceback (most recent call last): File "setup.py", line 7, in <module> ext_modules = [module1]) File "C:\Python26\lib\distutils\core.py", line 152, in setup dist.run_commands() File "C:\Python26\lib\distutils\dist.py", line 975, in run_commands self.run_command(cmd) File "C:\Python26\lib\distutils\dist.py", line 995, in run_command cmd_obj.run() File "C:\Python26\lib\distutils\command\build.py", line 134, in run self.run_command(cmd_name) File "C:\Python26\lib\distutils\cmd.py", line 333, in run_command self.distribution.run_command(command) File "C:\Python26\lib\distutils\dist.py", line 995, in run_command cmd_obj.run() File "C:\Python26\lib\distutils\command\build_ext.py", line 343, in run self.build_extensions() File "C:\Python26\lib\distutils\command\build_ext.py", line 469, in build_extensions self.build_extension(ext) File "C:\Python26\lib\distutils\command\build_ext.py", line 534, in build_extension depends=ext.depends) File "C:\Python26\lib\distutils\msvc9compiler.py", line 448, in compile self.initialize() File "C:\Python26\lib\distutils\msvc9compiler.py", line 358, in initialize vc_env = query_vcvarsall(VERSION, plat_spec) File "C:\Python26\lib\distutils\msvc9compiler.py", line 274, in query_vcvarsall raise ValueError(str(list(result.keys()))) ValueError: [u'path']
What can I do to fix this? Any help will be appreciated

For Win7 x64 machine Python 2.6 (x64) machine, you need to install
SDK de Microsoft Windows para Windows 7 y .NET Framework 3.5 SP1
See the instructions at
The commercial Visual Studio 2008 is for Python 2.6, 2.7 and 2.8 on the 32-bit x86 setup.
I would avoid installing the Windows SDK and VS 2008 for this.
I believe the problem you have is due to VS 2008 not having the 64-bit compilers. To check this, find your directory containing vcvarsall.bat (search in the VS 2008 directory for it C:\Program Files (x86)\Microsoft Visual Studio 9.0). Once you've found vcvarsall.bat, open a cmd prompt in the directory it's in and type
If it is not the problem, you will see
Setting environment for using Microsoft Visual Studio 2008 x64 tools.
If this is the problem, you will get back a message saying something about configuration. This is easy to fix.
The express version of VS does not have the 64-bit compilers. The solution is to also install the SDK but is messy and unreliable so MS have provided all the compilers together in a single download: http://www.microsoft.com/en-gb/download/details.aspx?id=44266
Once you have downloaded the compilers, you can follow my post here if it doesn't work straight out the box: pyusb 2.7 windows install error
