Anaconda install on Mac Big Sur Python cannot be opened

Question

I installed Anaconda.Navigator on my Mac running Big Sur and I can no longer use Jupiter Notebook to run python scripts. I get this error when I try to run any python: Python cannot be opened because of a problem. I get the following error report in the terminal when I type Conda I can see all help commands and when type in python I can see:

Python 3.8.5 (default, Sep  4 2020, 02:22:02) 
[Clang 10.0.0 ] :: Anaconda, Inc. on darwin

From the Anaconda GUI when I toggle to Extensions I can see all the extensions that have been installed. Yet it seems like it is not pointing to the Library correctly.

Any help would be greatly appreciated.

Thank you, Walter

If you look at your output, it's not pointing to the version of python you have linked in your PATH (`Python 3.8.5`), it's pointing to: `/Library/Frameworks/Python.framework/Versions/3.6/Resources/Python.app/Contents/MacOS/Python` Do you have Python 3.6 installed in that library location? — jaypb, Dec 17 '20 at 21:56
How do I change the path location either within Anaconda or install Python to this location? — Walter, Dec 18 '20 at 22:04
Anaconda advises against changing the path variable. Is your conda/pip/jupyter notebook command working from terminal? If not, try this method. https://stackoverflow.com/a/65514763/6713740 — rko, Dec 30 '20 at 23:26

It turned out that the old versions of python that I had installed were somehow interfering with the Anaconda install and Python 3.8 that it wanted to install. I deleted all the old versions found in the Python.framework folder including the folder. I did not touch the python2.7 that came installed with Mac's OS. Then I did a clean install of Anaconda Individual. One final hiccup was that the kernel was not running when I tried to open Jupyter Notebook so I had to manually set the kernel path with this

python -m ipykernel install --user

I found this fix on GitHUb

I hope this helps someone in the future.
