Try installing this  it s a known workaround for enabling the C   compiler for Python 2 7    In my experience  when pip does not find vcvarsall bat compiler  all I do is opening a Visual Studio console as it set the path variables to call vcvarsall bat directly and then I run pip on this command line

Here too I can reproduce this problem with scrapy and psycopg2  both require C   compiling   even though I have Microsoft Visual C   Compiler for Python 2 7 installed   It has to be noted that I use virtualenv  From your post I m not sure whether you do the same   Anyway I tried to skip the activation of the virtual environment  Then both scrapy and psycopg2 installed fine   My hypothesis  there is a conflict between this 2014 C   compiler for Python and virtualenv  I do not know why nor how to solve it  and I d be glad if someone can suggest a workaround

I was getting the same error in python 3 4 3 too and I tried using the solutions mentioned here and elsewhere with no success   Microsoft makes a compiler available for Python 2 7 but it didn t do me much good since I am on 3 4 3    Python since 3 3 has transitioned over to 2010 and you can download and install Visual C   2010 Express for free here  https   www visualstudio com downloads download-visual-studio-vs d-2010-express  Here is the official blog post talking about the transition to 2010 for 3 3  http   blog python org 2012 05 recent-windows-changes-in-python-33 html  Because previous versions gave a different error for vcvarsall bat I would double check the version you are using with  pip -V   C  Users B gt pip -V pip 6 0 8 from C  Python34 lib site-packages  python 3 4    As a side note  I too tried using the latest version of VC    2013  first but it required installing 2010 express    From that point forward it should work for anyone using the 32 bit version  if you are on the 64 bit version you will then get the ValueError    path   message because VC   2010 doesn t have a 64 bit compuler  For that you have to get the  Microsoft SDK 7 1  I can t hyperlink the instruction for 64 bit because I am limited to 2 links per post but its at  Python PIP has issues with path for MS Visual Studio 2010 Express for 64-bit install on Windows 7
