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.

Solution 1

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.

Solution 2

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...
