installing python module on windows 8

Question

I am doing a project in python where I have a very large dataset where I have to do a fisher exact test. This must be done 600,000,000 times so efficiency is quite important. However, with the scipy package this takes 50 hours, but I have read that https://pypi.python.org/pypi/fisher/ should be much faster. But I don't understand how to get it installed in Windows 8.

I have tried using: python setup.py install, this gives the error:

D:\Programmer\Python\Scripts\fisher-0.1.4>python setup.py install

running install
running build
running build_py
running build_ext
building 'fisher/cfisher' extension
error: Unable to find vcvarsall.bat

what is wrong?

You asked a [question with the same title](http://stackoverflow.com/questions/24288172/installing-a-python-module-on-windows-8) an hour ago that you deleted. Care to explain? — wnnmaw, Jun 18 '14 at 16:12
Note that you'll need Cython and a C compiler to build the package from source. — , Jun 18 '14 at 16:17
I have tried pip install fisher also. It gives another error, but I want paste it all into here since its quite long, but the last 3 lines is: Cannot export initfisher/cfisher: symbol not defined collect2.exe: error: ld returned 1 exit status error: command 'gcc' failed with exit status 1 — Acarbalacar, Jun 18 '14 at 16:37
You need a C compiler. VC++, or mingw, cygwin, whatever works for you. That's what the error is about. — , Jun 19 '14 at 08:22

This is how you do it:

Type into the Command Prompt window:

set path=%path%;C:\Python27\

And hit enter.

Use the complete path to the folder using CD.

eg: cd c:\Users\fisher-0.1.4

Then type python setup.py install

How is this different than what the OP has already tried (as shown)? – Jun 18 '14 at 16:21
I don't think he has invoked the interpreter. – Aaron Misquith Jun 18 '14 at 16:26
The OP has entered `python setup.py install`, and the first lines of output show that `setup.py` is indeed being run correctly. It's only at the stage where the C extension is being built (judging from the name) that things go wrong. – Jun 18 '14 at 16:29
I have python installed at D:\Programmer\Python I guess it shouldnt be exactly set path=%path%;C:\Python27\ then? I havent tried this before, so I need it to be absolutely clear for me to know what to do – Acarbalacar Jun 18 '14 at 16:33
Then there might be a chance that he has not installed VC++. – Aaron Misquith Jun 18 '14 at 16:35
@user3752939 then change it to D drive. – Aaron Misquith Jun 18 '14 at 16:37
does 27 refer to python 2.7? Since I have 3.3 Also, VC++ 2012 is installed – Acarbalacar Jun 18 '14 at 16:42
Yes.That is for 2.7. Instead of python27 type the folder name for 3.3 – Aaron Misquith Jun 18 '14 at 16:45
Unfortunately it doesnt work. I have written path=%path%;D:programmer\Python\ (this is where python is installed) and then python setup.py install. Still with the same error. Thanks for the help though – Acarbalacar Jun 18 '14 at 16:49
Check out the first answer about easy_install here: http://stackoverflow.com/questions/19830942/pip-install-gives-error-unable-to-find-vcvarsall-bat – Aaron Misquith Jun 18 '14 at 16:52
and it's not `path=` it's `set path=` – Aaron Misquith Jun 18 '14 at 16:55
Sorry typo, I did use set path. easy_install gives another error which I wont copy/paste here since it is very long – Acarbalacar Jun 18 '14 at 16:59
