Looks like something is wrong with the `PYTHONPATH` and the non-installed python cannot find the libpython.so. Is there a way I can reproduce this locally?

OK. I figured out what happened. So if we enable shared python build. Besides `PYTHONPATH`, we also needs to set `LD_LIBRARY_PATH`(on linux) or `DYLD_LIBRARY_PATH`(on macos) so what python binary can...

I will try to follow the instruction on [custom builders](https://devguide.python.org/testing/buildbots/#custom-builders) to test my fix.

Hi @zooba looks like I don't have write access to python/cpython so I can't test the code with buildbot-custom. I pushed my fix [here](https://github.com/kkpattern/cpython/tree/fix_test_venv_shared). I have tested it on linux...

We're also facing this issue. The fbsdk version we have is `9.2.0`. The `FBSDKPaymentObserver.m` changed a lot in the following versions. It has been refactored to swift in `15.0.0`. Maybe...

Installing all the editable packages at once works for us.

We also set `index-url` in our venv by `pip config --site set install.index-url "http://path/to/internal/pypi/server"`

> What exactly do this mean? There's a `pip.conf` file _in_ the `.venv` folder? Yes. If you activate a `.venv` then run `pip config --site set install.index-url "http://pypi.internal.com"`, there will...

It's convenient when we want to install some libs into a .venv across multiple sessions. For example, a developer may set up a local `.venv` for development and use it...
