Error while installing scipy on windows

Question

I am working on a windows machine and 2.7 version of python. I have already installed numpy and now I am trying to install scipy. I have tried installing it using the easy install command and by downloading a zip file and then running the setup.py file.

When I try installing it by the easy_install

c:\Python27\Scripts>easy_install scipy

I am new to python and I am not understanding why I am getting these errors. I don't see a folder in the Lib folder of Python27 and as expected I am getting an ImportError: No module named scipy error when I say import scipy on the terminal.

You don't appear to have a compiler installed to compile scipy and its dependencies. This is a common issue on windows. You'll need to install a compiler (the long route) or download the pre-compiled binaries for windows (usually much more user-friendly for packages you need to use on windows).

Individual binary and source packages (from scipy.org/install.html)

The maintainers of many of the packages in the SciPy stack provide “official” binary installers for common Windows and OS-X systems that can be used to install the packages one by one. These installers are generally built to be compatible with the Python binaries available from python.org.

I'd try grabbing the latest version from sourceforge at http://sourceforge.net/projects/scipy/files/scipy/

The superpack at sourceforge was useful. Got scipy installed on my x64 Windows 7 for Python 3.4. – Nikhil Girraj Jun 30 '15 at 07:09
I've solverd a similar problem (wrong compiler version) by downloading it from Microsoft: http://aka.ms/vcpython27. More help [here](http://stackoverflow.com/questions/26140192/microsoft-visual-c-compiler-for-python-2-7) – SiHa Jul 06 '16 at 11:56

Long I tried to establish a SciPy after setting numpy. I too used https://sourceforge.net/projects/scipy/files/scipy/ But I win64, but only under the win32 website. Download and install scipy-0.16.1-win32-superpack-python2.7.exe and now scipy appears in the installed modules.
