I am using Mac so cannot use msvcrt.
Thank you for your help.
The installation is failing because it's looking for python3 headers. Looking at https://pypi.python.org/pypi/getch there are two source distributions listed, getch-1.0-python2.tar.gz and getch-1.0.tar.gz.
For python 2 you need the former of those, but it looks like the latter one is being chosen (same thing happens for me). I'm not sure if/how pip is supposed to be able to know how to choose the correct one, but you can choose manually:
copying the link,
pip install https://pypi.python.org/packages/source/g/getch/getch-1.0-python2.tar.gz#md5=586ea0f1f16aa094ff6a30736ba03c50
works for me

I am trying to install big float on OS X but i am encountering multiple issues.
I have installed amp without any problem, but when I have tried to install mpfr I got this error:
Warning: mpfr-3.1.5 already installed, it's just not linked.
What does this mean? (I am using Homebrew).
Then, obviously, if I try to install bigfloat it doesn't work and i get this error:

You must install python-devel
In OS X try to uninstall and install again:
brew uninstall python
brew install python
Also according to this issue, Osx GCC (which is just a symlink to clang) doesn't ship with OpenMP support out of the box. You can install GCC with OpenMP.
brew install gcc --without-multilib
I already have the latest builds for leptonica and tesseract
tesseract 4.00.00alpha-365-gcf0b378
leptonica-1.74.1
libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
i have also installed all dependencies like python-dev

Finally fixed the issue
completely removed tesseract and leptonica from the system and built everything from source
the debian package leptonica-dev for ubuntu 14.04 was the problem
these are the current builds i've compiled
$ tesseract -v
tesseract 3.04.01
leptonica-1.74.1
libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8
I want use Fabric when I product my project in AWS Ubuntu. When I read about Fabric, it required python 2.5~2.7, so I create Python virtualenv on Mac OS X:
pyenv virtualenv 2.7.5 fabric
mkdir fabric
and I run pip install fabric
(fabric)fabric $ pip install fabric
but it has 2 errors

Some people tell me "you should install pycrpto" so I install pycrpto
pip install pycrpto
but it has the same error when I pip install fabric. I found this solution link, so I run:
brew install gmp
export LIBRARY_PATH=/usr/local/lib
pip install pycrypto
but it has the same error and second solution is link
$ bunzip2 gmp-5.0.5.tar.bz2
but it has another error:
bunzip2: Can't open input file gmp-5.0.5.tar.bz2: No such file or directory.
I can't understand why fabric doesn't install...
It's a bug in Python <2.7.8. See pyenv#273.
You can fix it by patching _sysconfigdata.py:
$ export p=/Users/andrei/.pyenv/versions/2.7.6
$ sed -i -e "s#python.exe#${p}/bin/python2.7#g" "$p/lib/python2.7/_sysconfigdata.py"
I'm running openSUSE Leap 42.1 and I just tried to update all the software in pip, using the following command:
for i in $(pip list|awk '{print $1}'); do pip install $i --upgrade;done
This hit a few errors, I had some missing devel dependencies, which I managed to fix, and most of the packages then updated fine, but one continues to fail, and I'm not sure why. The errors at this point became a bit cryptic and my google-fu was unable to find the answer. Can anyone advise why I'm getting this error, and whether there is a way to fix/work around?

What would cause this? Something about setting include directories?
The issue you're seeing with installing fastcluster is related to this previous question - the compiler is not looking in the correct directory to find the numpy headers. You can use more or less the same solution as given in the accepted answer:
Download and untar the source for fastcluster
$ pip install fastcluster --download='.'
$ tar -xzf fastcluster-1.1.17.tar.gz
$ cd fastcluster-1.1.17/
Edit the setup.py file to add the output of numpy.get_include() to the include_dirs= argument for the Extension:
import numpy
...
ext_modules=[Extension('_fastcluster',
['src/fastcluster_python.cpp'],
extra_compile_args=['/EHsc'] if os.name=='nt' else [],
include_dirs=[numpy.get_include()]
)]
Install fastcluster:
$ python setup.py install
Let the fastcluster maintainer know that his package is broken :-)
