installing pandas using pip in EPD7.3 without upgrading numpy

[Andreas Hilboll]

According to
http://pandas.pydata.org/pandas-docs/stable/install.html#dependencies,
pandas 0.8 requires numpy >= 1.6.1. When installing pandas via pip on a
system with EPD7.3 installed (which ships numpy 1.6.1), pip downloads
numpy 1.6.2 and installs it as a dependency.

I figure this is because I supplied the ``--upgrade`` flag to pip. This
was necessary because EPD already includes pandas 0.7.3.

Am I missing a point, or is pip just not the way to go in this case?

Cheers,
Andreas.

You should probably uninstall the EPD egg of pandas first. Upgrading
it via pip still leaves some metadata that will make enpkg still think
that you have the old pandas installed.

$ egginst --remove pandas

$ pip install pandas

But in general, you should be able to upgrade just the requested
package and not its dependencies like so:

$ pip install --upgrade --no-deps pandas
