The message Unable to find vcvarsall.bat means it's looking for the Visual C++ compiler and can't find it installed. If you want to develop on Windows, I believe this compiler is freely available in Visual Studio 2008. Some all-in-one distributions use workarounds for different compilers on Windows, commonly mingw32 (Python(x,y) uses this option), or pre-compiled binaries (the most used set I'm aware of is provided by Christopher Gohlke: http://www.lfd.uci.edu/~gohlke/pythonlibs/) though you obviously can't easily develop using a precompiled binary. Personally, I think you'll be happier all around if you develop on a *NIX like Fedora, Ubuntu, Linux Mint, or Scientific Linux. On Tuesday, April 9, 2013 1:37:28 PM UTC-5, abid rahman wrote:

Hi,

I ran into a problem with scikit installation in windows 7. I am using python 2.7 32 bit. python setup.py install shows error : Unable to find vcvarsall.bat.

Any idea what it is? I googled and tried a lot of hacks, but still the same error. Any idea what it is?

Meanwhile, I will switch into Fedora for backprojection work !!!

Regards
