Python Pip install Error: Unable to find vcvarsall.bat. Tried all solutions

I tried to install Scrapy for Python 2.7.8 (anaconda 2.1.0) 32-bit using

    pip install scrapy

And I got this error

     error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).

I have followed the solutions found in these stackover flow questions. Nothing worked.

Getting "error: Unable to find vcvarsall.bat" when running "pip install numpy" on windows7 64bit

How do I point easy_install to vcvarsall.bat?

pip install MySQL-python returns unable to find vcvarsall.bat

This is the error, and a few lines above and below it:

I have both Microsoft Visual Studio 12.0, and Microsoft visual C++ compiler package for Python 2.7, both of which have the vcvarsall.bat file.

I have a system variable that is called 'VS120COMNTOOLS' and is its path is set to

    C:\Program Files\Microsoft Visual Studio 12.0\Common7\Tools\

I also added both paths to my environment variables. I've also tried just adding one, and then the other. My Path looks like this

    C:\Program Files\Java\jdk1.7.0_25\bin;\Python27;\Python2\python.exe;C:\Python27\Scripts\;C:\Users\San\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\;C:\Program Files\Microsoft Visual Studio 12.0\VC\;

I also updated by my setup tools (I think to version 8), which should autodetect Microsoft Visual C++ Compiler for Python 2.7. However, I'm still getting the same error.

I have also tried using

    easy_install scrapy

And I get this error

    error: Setup script exited with error: Microsoft Visual C++ 10.0 is required (Un

able to find vcvarsall.bat).

I also have the following in my registry

    HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\9.0\Setup\VC\ProductDir
    HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\12.0\Setup\VC\ProductDir

I have tried all suggestions and found my own simple solution.

The problem is that codes written in external environment like C need compiler. Look for its own VS environment, i.e. VS 2008.

Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat. I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLS as variable name and gave the value of VS120COMNTOOLS.

You can find my step by step solution below:

  1. Right click on My Computer.
  2. Click Properties
  3. Advanced system settings
  4. Environment variables
  5. Add New system variable
  6. Enter VS90COMNTOOLS to the variable name
  7. Enter the value of current version to the new variable.
  8. Close all windows

Now open a new session and pip install your-package
