I am running PortablePython_1.1_py2.6.1 on a USB stick. My code relies on some modules that are not preinstalled. Does anyone know whether it is possible to add new modules to a portable python installation? Simply copying in folders into site-lib does not seem to work.
What does import sys; print sys.path say? It should be the list of directories and zipfiles where Python (portable or otherwise) looks for modules to import. Just copy your modules into one of those directories or zipfiles, or sys.path.append('/whatever/dir') if you have your modules in /whatever/dir and want to keep them there (the latter approach will last only for the current session, be it interactive or a script's execution).
This closed question was actually asked for Portable Python 3.2. I have found a nice way to install modules with Windows :
download the zip archive of the distribute module
install it by typing
MyPythonPath\App\python MyDownloadPath\setup.py install
in a DOS commander
Now Easy Install is installed in folder MyPythonPath\App\Scripts. So type e.g.
MyPythonPath\App\Scripts\easy_install-3.2 numpy
to install the numpy module.
