I am getting following error in installing Cassandra driver for python.
Command "c:\python33\python.exe -u -c "import setuptools, tokenize;__file__='c:\

Any one have any idea about this ? What am i missing ?
Following errors were also there when i run pip install cassandra-driver

I tried it in an environment missing compiler paths and observed something similar. I think it's a problem in setuptools error handling when it doesn't find what it's expecting. The easiest way I've found is to use the VS Command Prompt shortcut installed with Visual Studio:
Perhaps the easiest way to do this is to run the build/install from a Visual Studio Command Prompt (a shortcut installed with Visual Studio that sources the appropriate environment and presents a shell).

Can anyone give me a clue? Thanks in advance.
OK, finally I get this tricky problem solved.
It's all because of lack of compiler on the windows system, because I didn't install VS or any of other compilers.
So I managed to install a substitute one:
http://mingw-w64.org
after installed, run cmd like this(for 64bit system):
python setup.py install build --compiler=mingw64
ofter this, every thing works smoothly.
Hope this helps to someone get stuck as me.
I am trying to install the Python module simplecrypto on a Windows machine. To do this I run the following:
C:\Python36\Scripts>pip install simplecrypto
However, upon running this partway through the installation process I receive the following error:

Why is this the case?
An error occurs when it attempts to install PyCrypto, which is a requirement of the package. The GitHub README mentions:
If the dependency installation fail on Windows, you may want to use a
prebuilt installer. If you wish to compile it I suggest using the
Mingw tools as indicated here.
Install it from here and then compile by
install MinGW with C++ Compiler option checked add C:\MinGW\bin to
your PATH in PYTHONPATH\Lib\distutils, create a file distutils.cfg and
add these lines:
[build] compiler=mingw32
I was trying to install 'ffnet' module in Python but even after installing Microsoft Visual Studio C++ and mingw32.
But these are the errors which are showing up:

Please anyone Help me with this.
On Windows + Python-3.5 fortran extensions cannot be built
anymore with f2py and mingw32 compilers, because of new MSVC used for python build. See: Build fortran extension on Windows with gfortran and MSVC
Maybe you could try python 3.4 instead?
So, I have going over this back and forth, I tried several of the solutions on this forum, none worked.
I have pip3 installed, Python 3.4, Visual Studio 2015 on Windows 10.
Now whenever I run the installing for a new module manually or through pip3 I get the following error:
Say I use the cmdline as such:
pip3 install numpy
I get :

Please help, considering to just use linux with python... less issues
This is based on #Jim answers in the comment section, basically make sure that you have the C++ compiler and windows SDK installed!
My problem was that when I installed Visual Studio, I did not select the windows SDK.
I've been working on a python script, first using the Psychopy compiler, which already included all I needed, but now I need to make it the more independent as possible. I have the script working on a Windows computer, but I also want it to work in OSX.
The script uses pyglet and I followed this post in order to install it. However, when I reach the latest step, which is installing PyObjc, I have the following error:
40 warnings and 1 error generated.
error: command '/usr/bin/clang' failed with exit status 1

Why does this error appears? What can I do to solve it?
Terminal post：
xcode-select --install
may be can help you.
Try installing pyobjc separately first.
On OSX 10.7 or 10.8, try:
env CC=clang pip -U pyobjc-core
env CC=clang pip -U pyobjc
On OSX 10.9, try:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install pyobjc
