Installing to: .frozen/

[Johnl52]

I'm trying to set my pico W as a mqtt client. I installed upip, then I entered the following

upip.install("micropython-umqtt.robust")

It says it is "Installing to: .frozen/" per the couple of videos I watched it should be installing to my lib folder and I get this message

Installing to: .frozen/
Warning: pypi.org SSL certificate is not validated
Installing micropython-umqtt.robust 1.0 from https://files.pythonhosted.org/packages/31/02/7268a19a5054cff8ff4cbbb126f00f098848dbe8f402caf083295a3a6a11/micropython-umqtt.robust-1.0.tar.gz

The file robust.py is not in the lib folder, I wouldn't think it is but that's what I should get.

Why does it install in the frozen folder, where ever that is, and not the lib folder?

Thanks
John
