The main problems are :
You need Java 1.6 or later to be installed and in your PATH variable. But if you manage to read this then you obviously have got Java in your PATH !
Not having Python installed and in your PATH variable. Make sure you can start Python from your standard shell or command window.
If you get this error :
Then
the problem could be because
on Linux you do not have LD_PRELOAD not pointing to your Python shared object. The solution is to define LD_PRELOAD and start Fable again.
on MacOSX you have to have a smybolic link from
libjep.dylib to /Library/Java/Extensions. You can do this like this
:
sudo ln -s
$FABLE_HOME/plugins/jep_2.0.1/lib/macosx/libjep.dylib
/Library/Java/Extensions/libjep.jnilib
on Windows, Linux or MacOS this can happen because you do not have the python package listed in the window installed. You need the following Python packages installed – NumPy and PIL. This should also be packaged with fable in $FABLE_HOME/python/$platform
If the package not found is fabio then probably
PYTHONPATH is not correctly positioned before starting fable.
PYTHONPATH must contain the following
:
$FABLE_HOME/python/fabio/$platform/
where $platform
is one of win32, linux, or macosx.
If you are an expert user
you can set PYTHONPATH to point to your local copy of PolyXSim.py.
