Unable to find VCVarsall.bat using Python 2.7

Question

I am working with win 7. Installed Python 2.7. I am trying to setup the source code downloaded from "http://effbot.org/downloads#tkinter3000" tkinter3000-1.0-20031212.zip [57k] it throws this error:

I don't have visual studio. Please suggest a workaround to move ahead.

You need a compiler. Either Visual Studio or Ming32 provides it. — Martijn Pieters, Oct 30 '13 at 17:27
and the guy had other tool installation problem.. i a have some other issue — Prag Rao, Oct 30 '13 at 17:27
u mean to say .. without compiler i will not be able to move.... — Prag Rao, Oct 30 '13 at 17:28
I only see binaries for Python 2.6 and earlier: http://effbot.org/downloads#tkinter3000, so yes. — Martijn Pieters, Oct 30 '13 at 17:31
can you please provide any link for downloading ming32 for win7 — Prag Rao, Oct 30 '13 at 17:35
What compiler do you have installed? I had the same bug but was using MinGW so that other question (http://stackoverflow.com/questions/2817869/error-unable-to-find-vcvarsall-bat) solved my issue... — Michael Clerx, Aug 25 '14 at 22:41

In order to compile certain Python 2.7 components you need a c compiler installed. The compiler expected when looking for VCVarsAll is Microsoft Visual C++. Microsoft has released a redistributable of the C++ Compiler for use with Python 2.7 that can be retrieved from the following link.

I had the same problem as you and, as explained here, for Python 2.7 you should use the 3.5 version of the Windows SDK which comes with a C compiler.

After installing you have to call the SetEnv.Cmd script that will to all the trick with the environment variables. I call it with SetEnv /x64 /release, but you should check for aditional flags.

I had a problem with my version (German) of Windows 7 and the SetEnv.Cmd was not working properly. This is because the variable names were wrapped between !! (exclamation marks) instead of %% (percentage symbols). I just replaced them manually and it worked fine...

Download Microsoft Visual C++ Compiler for Python 2.7 from

http://www.microsoft.com/en-us/download/details.aspx?id=44266

Then don't forget to load setuptools and not distutils, because distutils has not yet been updated to support this compiler.
