Using PIP to install jupyterlab-CodePudding

So I recently decided that I wanted to do Python again but this time I wanted it for AI, so I ended up wanting to use Jupyter Notebook. However, when I use the command pip install jupyterlab, it gives me the following error.

dyld: Library not loaded: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation Referenced from: /Library/Frameworks/Python.framework/Versions/3.7/Resources/Python.app/Contents/MacOS/Python Reason: image not found zsh: abort pip install notebook

So I decided to check my echo $PATH and I got this

/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.8/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/usr/local/share/dotnet:~/.dotnet/tools:/Library/Frameworks/Mono.framework/Versions/Current/Commands

So what I understood from this is that my system is using python 3.9? <- I'm not sure about this to be completely honest. Going back to the pip install jupyterlab it gives another error in which is gives me this

All in all how do I use pip to install Jupyterlab? I am very new to all this so I didn't know what the right information was to give so I gave everything I saw.

Thank you :)

Either you do it through anaconda: https://docs.anaconda.com/anaconda/install/index.html

Or, it seems you are using Python 3.7. It is recommended to use pip3 in that case. Have you tried pip3 install jupyterlab?
