Unable to install pandas

[devavrat]

I have followed earlier posts for installing pandas. I have been having trouble installing it. Below are some details.

Mac Lion 10.7.5
Installed Cython (using pip install, which utilized llvm-gcc-4.2, for example)

Trying to install pandas using pip install from distribution or from git fails giving error:

pandas/index.c: In function ‘__pyx_f_8datetime__dts_to_pydatetime’:

pandas/index.c:10644: warning: implicit conversion shortens 64-bit value into a 32-bit value

lipo: can't open input file: /var/tmp//ccJ7Amtv.out (No such file or directory)

error: command 'llvm-gcc-4.2' failed with exit status 1

---

Cleaning up...

Downloading source and installing by running python setup.py install gives error

File "setup.py", line 91, in build_extensions
numpy_incl = pkg_resources.resource_filename('numpy', 'core/include')

Any help ?

It looks like you need to install numpy manually before installing pandas see #3074 and this PR for details #2740

Thanks, Katy. This is what worked for me --

Step 1. Execution of the following two commands to set the distribution right

curl -O http://python-distribute.org/distribute_setup.py
python distribute_setup.py

Step 2. Cloning git source, running following two commands from the pandas/ direction 👍

python setup.py install
python setup.py build_ext --inplace

Hope this will be of help to someone else.
