These are the steps I followed

sudo python27 get-pip.py
sudo yum install git
git clone https://github.com/pubnub/python && cd python/python
sudo update-alternatives --config python
sudo yum install python-devel
sudo yum install gcc
Thanks
You need to install Python's header files. How you do that will depend on your operating system.
On Debian or Ubuntu, for example, something like
sudo apt-get install python-dev
should do it.
On Fedora / CentOS / Red Hat, try
sudo yum install python-devel
The solution for this, I had to follow these steps

Check ldconfig softlink for python and find out what its pointing to
ldconfig -p | grep python2.7
libpython2.7.so.1.0 (libc6,x86-64) => /usr/lib64/libpython2.7.so.1.0
This shows that it was looking for a wrong softlink and I changed the soft link like this
sudo ln -s /usr/lib64/libpython2.7.so.1.0 /usr/lib64/libpython2.7.so
and then had to run pip like this
sudo /usr/local/bin/pip install pubnub -- Location of pip installed
Worked Pretty Good

I'm trying to install openfst like so:
wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.8.2.tar.gz
tar zxvf openfst-1.8.2.tar.gz
cd openfst-1.8.2
./configure --enable-python
make
sudo make install
but during the Python installation step, I get:

I don't really understand why, given that seemingly we just installed the necessary fst components?
Is this an issue with the conda installation or something else?
I'm using Miniconda with conda version 4.13.0
Any pointers would be appreciated!
I think the problem is the openfst itself:
OpenFst no longer produces a fst/types.h
If you just want to use wrapped python or not a C++ dev, you should use anaconda package: OpenFST anaconda as #kotatsuyaki suggest. Or you can install from source with version 1.7.x
i have kubuntu 15.10 with python2.7 and python 3.4m installed
if i install cxfreeze with sudo apt-get cx_freeze it is installed with no issues but the problem is when i compile my python modules the are compiled for python2.7 not python 3
So i am trying to build cx_freeze from source and i am facing this error when i run sudo python3 setup.py build
here's the error

Install zlib1g-dev :
sudo apt install zlib1g-dev
then install cx_freeze for python:
pip install cx_freeze
I've tried that on Ubuntu 18.04 and Python 3.6 and worked.
I had exactly the same problem. As suggested in this answer you just need to install the dependencies first:
pip3 install zlib1g-dev
Then sudo python3 setup.py build
Getting the following error when trying to install Pandas (0.16.0), which is in my requirements.txt file, on AWS Elastic Beanstalk EC2 instance:

I'm running on 64bit Amazon Linux 2015.03 v1.3.0 running Python 2.7 and previously ran into this same error on a t1.micro instance, which was resolved when I change to a m3.medium, but I'm running an m3.xlarge so can't be a memory issue.
I have also ensured that gcc is installed as a package in .ebextensions/00_gcc.config:
packages:
yum:
gcc: []
gcc-c++: []
For pandas being compiled on Elastic Beanstalk, make sure to have both packages: gcc-c++ and python-devel
packages:
yum:
gcc-c++: []
python-devel: []
Install python-dev
sudo apt-get install python-dev
For python3
sudo apt-get install python3-dev
on ec2 instances if you run into gcc error; try this
sudo yum install gcc python-setuptools python-devel postgresql-devel
sudo su -
sudo pip install
I had to upgrade amazon's EC2 pip. You can do this by editing the .config file in .ebextensions:
sh
commands:
00_update_pip:
command: "/opt/python/run/venv/bin/pip install --upgrade pip"
I solved this issue by ssh'ing in to the EBS machine and updating pip
pip install -U pip
I am using openpyxl python package in my application. I am getting the following message when using the same.

Openpyxl requires lxml version 3.2.5 or above, and the version in my machine is 3.2.0. When I try to upgrade lxml to the latest version ie
3.3.5, it is getting interrupted with the following message.

I need help in resolving the issue.
PS:- I have already installed lxml dependent packages python-dev, libxml2-dev and libxslt1-dev in my machine.
sudo pip install --upgrade lxml
On Ubuntu (and other Debian derivatives), before you build some piece of software, ensure that its build dependencies are installed. Using your example, run this:
sudo apt-get build-dep python-lxml
That is likely going to require a whole bunch of packages, one of which is zlib1g-dev, as mentioned.
I think what you're missing is zlib1g-dev.
sudo apt-get install zlib1g-dev
Running above command will solve the issue.

Installing SciPy with pip
I want to install a new version of SciPy which is 0.11.0 and the current version which I have is 0.9.0.
It is installed by this command:
sudo apt-get install python-scipy
I have tried installing 0.11.0 from sources, but I could not.
Is there already an apt-get for 0.11.0?

I have asked this question [here], but the issue is not solved yet.
Any thoughts?
If you have all the basic prerequisites installed as described in the INSTALL.txt file, it should be fairly straightforward by doing a:
sudo python setupy.py install
from within the directory where you extracted the scipy0.11.0 tarball. This should make the library inside your current default Python version.
You can check whether you have the prerequisites by just running:
sudo apt-get install python python-dev libatlas3-base-dev gcc gfortran g++
as explained again in the INSTALL.TXT.
