Hello everyone,

I’ve encountered the problem with authentication at our JupyterHub. I want to use GitHub auth and restrict access only to members of our organisation. Unfortunately, the littlest jupyter hub uses oauthenicator version 0.10.0, here are the logs I get after reloading Jupyter hub with `sudo tljh-config reload hub` and using `sudo journalctl -u jupyterhub`:

```auto

```

Config option `allowed_organizations` is not recognized because it was introduced later than in 0.10.0 version. I tried to update it with `pip install --upgrade oauthenticator`, and when I use `pip freeze` I see the correct upgraded version, but it doesn’t help - when I reload jupyter-hub, it still uses 0.10.0 version.

I’m updating it in the “base” environment which is created by the littlest jupyterhub by default. Maybe I should do it elsewhere?

According to the source code the hub environment is under `/opt/tljh/hub`

Thanks a lot, I used `/opt/tljh/hub/bin/python -m pip install --upgrade oauthenticator` and it solved my problem.
