Problems installing Pandas

Question

I am unable to install Pandas on my Linux server. I am using virtualenv but I tried installing Pandas without that but no luck.

Numpy installs with a lot of warnings.

You are using pip version 6.0.8, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I tried creating swap file just to eliminate memory issues, that did not help.

I am able to install pandas with

sudo apt-get install python-pandas

But this install pandas for system default Python 2.7. I am using python 3.4 in virtual environment.

Any suggestions?

I noticed that my errors started with this:

You are using pip version 6.0.8, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting numpy
 Using cached numpy-1.11.0.tar.gz
 Running from numpy source directory.
Installing collected packages: numpy
 Running setup.py install for numpy
Note: if you need reliable uninstall behavior, then install
with pip instead of using `setup.py install`:
 - `pip install .` (from a git repo or downloaded source
 release)
 - `pip install numpy` (last Numpy release on PyPi)

This finally fixed my problem:

Upgrading pip globally (old pip version 6.0.8 to new version 8.1.2):

sudo pip3 install --upgrade pip

In virtualenv,

pip3 install numpy pip3 install pandas
