Easy way to resolve --- Python 3.5 in win8 (Unable to find vcvarsall.bat)

• pip install numpy

However, If you don’t have a C/C++ compiler installed, you can get the following error while you are trying to install Numpy on Windows 7 or 8.1:

• error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat)

Easiest way to install Numpy is using the (unofficial) binary packages from Christoph’s site.

•  Download the binaries from the link below:
  • http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
    • 32-bit: numpy‑1.9.2+mkl‑cp27‑none‑win32.whl
    • 64-bit: numpy‑1.9.2+mkl‑cp27‑none‑win_amd64.whl
• Python 2.7.9+/3.5+ ships with Pip, if you are using Python 2.7.8/3.5 or below install Pip by following the steps as follows:
  • Download get-pip.py from the link below and save it as .py:
    • https://raw.github.com/pypa/pip/master/contrib/get-pip.py
  • Then run the following command from command prompt as administrator:
    • python get-pip.py
• Open command prompt and navigate to the directory where pip3.5.exe is located:
  • cd C:\Python35\Scripts
• Run the following command and install Numpy (you can copy the downloaded binary to the above directory beforehand or enter the full path to the downloaded file)
  • pip3.5.exe install numpy-1.10.4+mkl-cp35-none-win_amd64.whl
