virtualenv has the switch

and the switch
--no-site-packages (to expclude all site packages)
Does anyone know an easy way to include just a few site-packages?
for example (PySide, but not PyQt)
The reason I'm asking is following.
Some site packages are sometimes raher huge or sometimes refuse to
compile on certain hosts.
as these packages are already part of the site packages I'd like to
include them.
You might wonder why I care whether I have more site packages than I
need. As long as I don't import them, I shouldn't care about it.
If I really wanted to replace a version I could use pip install -U.
However sometimes I'd like to have a test environment where want to
be
sure, that no module can find certain other modules. so they should
not be visible.
at the moment I make some experiments with pyinstaller and the module
pythonqtbindings. and there I'd like to be sure that no PuQt files
end up in the generated code.
The only idea, that I have so far is to
run virutalanv with --system-side-packages and to manually remove
modules I don't want or to
run virtualenv without this switch and to manually add links for site
packages, taht I want. both options don't really feel right for me.
Is there any other way?
You could build a virtual machine, installing only your VIP modules, and create
virtual environment on this virtual machine, using the system site packages.
Yeah that's an option.
However I guess in this case it's probably faster to write a script,
that 'post-processes' the virtualenv and just deletes files / symlinks,
that are not desired. Definitely not elegant, but probably OK. On the
other hand a VM migfht help finding out which files to keep.
