Installation in terminal

installpackage-managementpython

I am trying to install a few software packages on my Mac os X 10.6.8. The packages are the python libraries:

networkx (graph library)
matplotlib (visuzlization)

It seems that with matpotlib I also need numpy and scipy. Anyway, what is the easiest way to install packages with a mac? I have used pip, and easy install. They both seem to install everything correctly, but nothing works after I install. It appears during upgrades that the latest version does not override the previous version of the package as it should.

In the past I have used Ubuntu seamlessly, and now my mac has been giving me some trouble with installation. All help is greatly appreciated!

The reason why Ubuntu works is that it has a package manager for all code, that is python and binaries. pip is a python installer and works in OSX for all pure python packages and simple C packages but seems to have issues with the more complex ones.

The nearest think to Linux's package managers are the package managers that deal with code ported from other Unices e.g. Macports, Homebrew, Fink. With choose one and one only as they can conflict (I use macports) and then use it for all possible ports.

In your case installing matplotlib would automatically install python, numpy, scipy etc

How about:

On the Ubuntu machine, make a ZIP file of the installation package.
Copy this file across to the Mac, using your existing sharing setup.
Expand it on the Mac and run it.

Edit The actual solution can be found in the comments below: use sudo mkdir /media/test; sudo mount -t hfsplus /dev/cdrom /media/test to mount the CD on the Ubuntu machine.

You can use virtualenv to create a local "copy" of the Python installation that's owned and easily manipulated by you. The advantage to using virtualenv is you can make many copies of the same version of Python, but with different versions of similar packages installed, and then switch between them with the virtualenv command line.

This lets you use different versions of libraries in different projects or incompatible libraries.

To install virtualenv:

sudo pip install virtualenv

And now you can use it yourself, without sudo, to create a virtual python owned by you:

mkdir -p ~/Development/mypythonproject
cd ~/Development/mypythonproject
virtualenv .venv
source .venv/bin/activate

For example:

IanCsiMac:~/Development/keybase-python |ruby-2.1.2| [git::develop]
> which python
/usr/local/bin/python

IanCsiMac:~/Development/keybase-python |ruby-2.1.2| [git::develop]
> source .venv/bin/activate

(.venv)
IanCsiMac:~/Development/keybase-python |ruby-2.1.2| [git::develop]
> which python
/Users/ian/code/keybase-python/.venv/bin/python

(.venv)
IanCsiMac:~/Development/keybase-python |ruby-2.1.2| [git::develop]
> deactivate

IanCsiMac:~/Development/keybase-python |ruby-2.1.2| [git::develop]
> which python
/usr/local/bin/python

You can virtualenv-install in your ~ directory if you want a default python that you control to be available at all times like so:

cd ~
virtualenv venv

And now you've got ~/venv/bin/pip available to you. You can modify your ~/.bash_profile and add:

source venv/bin/activate

Right at the end of it to have your virtualenv available by default in your shell.
