Set PYTHONPATH, when virtualenv is activated

Question

This moment, I am using pyenv + venv to manage Python versions and specific libraries. My project layout looks like this:

1. dir1
   • subdir11
   • subdir12
   • subdir13
2. dir2
   • subdir21
   • subdir22
   • subdir23

My goal is, once venv is activated dir1 and dir2 to be inside sys.path. Basically, I solve this task but I really do not like solution. I added custom PYTHONPATH inside venv under bin/activate file and everything works fine. This is not so flexible from deployment point of view. Does venv provide some hooks for this ? For example: set customer environment variables once venv is activated or run some function or something like this. I do not like idea, to modify bin/activate file on every machine.
P.S I know about packaging stuff and setuptools, but for this project I can not use it.

Any ideas ?

Thanks !

Another possibility (which is usually what I use and avoids going into you venv source code) :

Create an activate.sh script where you export path to your modules AND activate venv ie :

source venv/bin/activate
export PYTHONPATH=$PYTHONPATH:$(pwd)

then you can just do source activate.sh instead of source venv/bin/activate and you will have both actions at once.
