Meltano

Trying to run my custom extractor which depends on Pandas. Pandas is already installed in the tap venv using Poetry. It's in site-packages but when I run `meltano run` I get `ModuleNotFoundError: No module named 'pandas'`.

My Meltano is installed using system wide pip (installed via Pyenv)

Make sure the custom extractor has it as a dependency, I'd assume you used the singer-sdk to build the tap? If so then check out `pyproject.toml`  <https://github.com/meltano/sdk/blob/main/cookiecutter/tap-template/%7B%7Bcookiecutter.tap_id%7D%7D/pyproject.toml>

venvs are created and meant to be fully isolated from each other(including from site-packages)

&gt;  Pandas is already installed in the tap venv using Poetry
Then maybe you added the package after you installed with Meltano? If so run a `meltano install --clean`

Meltano creates a different venv in `.meltano/extractors` that has your deps, so if you changed dependencies after you installed the tap that would explain this
