Installation (Win)

i heard that the easiest way to install all of these packages is from here:

Installation (Mac)

Developer Tools

you need to install the apple developer tools that ship with OSX.

Python 2.5

you need a more recent version of python than what ships with OSX. install python 2.5 from here: afterwards, you have to make sure that this is the python version that is actually used when you type 'python' in your terminal window. in order to chech that, type 'which python':

 % which python

in order to add /usr/local/bin to your path, put the following line into your ~/.cshrc file:

 setenv PATH /usr/local/bin:${PATH}

(this is the syntax for the cshell. if you are using the bash, you have to put something like 'export PATH=/usr/local/bin:${PATH}' into your ~/.profile file)


install numpy from the same web page give it a try by running 'python' and within python run the commands

 import numpy


get ipython from here:

 tar xvzf ipython-0.8.1.tar.gz
 python install

i recommend to link ipython into your /usr/local/bin directory:

 sudo ln -s /Library/Frameworks/Python.framework/Versions/Current/bin/ipython /usr/local/bin

now you should be able to start ipython in a terminal window:


you can customize ipython (for example the colors) by modifying the file



install matplotlib from

you can give it a try by running

 ipython -pylab

and within ipython, run a simple plotting command like:


you can customize matplotlib by modifying the file


if this file does not exist, you can get a copy here:

 mkdir ~/.matplotlib
 cp /Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc ~/.matplotlib

i recommend to change the following setting:

 text.usetex : True

(of course, for it to work, you need to have latex installed)


you can essentially follow the description on this web page:

afterwards, you should run (within ipython)

 import scipy

at the moment, all but 2 tests should run fine. the two remaining tests will be hopefully fixed soon.

Installation of eric (Mac)

Qt 3

get qt3-mac here: and move it to the /tmp directory.

 sudo su
 cd /usr/local/
 tar xvzf /tmp/qt-mac-free-3.3.8.tar.gz
 cd qt-mac-free-3.3.8
 export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/Qt-mac-free-3.3.8/lib
 ./configure -thread -static


get QScintilla1 here:

 tar xvzf QScintilla-1.71-gpl-1.7.1.tar.gz 
 cd QScintilla-1.71-gpl-1.7.1/qt
 sudo make
 sudo make install


get sip here:

 tar xvzf sip-4.7.tar.gz
 cd sip-4.7
 python -k -n
 sudo make install


get PyQt3 here:

 tar xvzf PyQt-mac-gpl-3.17.3
 cd PyQt-mac-gpl-3.17.3
 python -w -k -y qt-mt

make sure that the qtext module is mentioned as one of the modules that will be built!

 sudo make install


get eric3 here:

 tar xvzf eric-3.9.5.tar.gz
 cd eric-3.9.5
 sudo su
 export DYLD_FALLBACK_LIBRARY_PATH=/usr/local/Qt-mac-free-3.3.8/lib

start eric:
