Encountered problems pip installing at two different levels.

[oldspammer]

Copilot advised me to try cython, and got me to also install jupyter. When installing Jupyter, it was having extreme troubles trying to get nbconvert to also install properly. I am on Windows 10 Professional, latest Windows update as of right now. I have python 3.11 installed as of a couple of weeks ago. For about 20 hours, it was working on installing nbconvert of various versions when I got sick of waiting for the thing to get back to the command prompt. I am running MS VS MSVC++ 2022 professional preview edition. I then tried to pip install nbconvert.

Here are the diagnostics that claim a problem was encountered. I am running this at the cmd prompt of a regular user windows 10 professional of the latest windows update, etc.

The Copilot AI was provided this same information, and it suggested that I install Rust, and Cargo to get this thing going, but why should I have to do that?

[takluyver]

It appears that for some reason it didn't find the pre-built packages which exist for rpds-py, so it fell back to trying to build from source. I'm not sure why from your description, though - there are wheels for Python 3.11 on Windows.

It also looks like something went wrong with dependency resolution - it's going back through many versions of nbconvert & jupyter_core trying to find a set of versions that all claim to be compatible. This is almost certainly the wrong thing to do, but resolving big webs of dependency constraints is hard. If you see this again, try telling it explicitly to install the latest version (pip install nbconvert==7.16.4), which might at least get it to tell you which packages seem to be incompatible.
