Solving environment failed (installing mamba with conda)

[ursaursic]

I had some issues installing mamba with conda on MacOS (following instructions). I found the solution - this might be helpful to someone who would struggle with the same issue.

I have the most recent version of anaconda (installer version Anaconda3-2022.10-MacOSX-x86_64), together with python3.9, but when installing mabma with
conda install mamba -c conda-forge
I get this:
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed ...

It takes a lot of time and never manages to solve the environment.

It turns out that anaconda can be a bit messy because there are already so many packages installed in the base environment.
In this case, spyder is causing problems.

This was a solution for me:

1. uninstall spyder using conda
2. install mamba using conda
3. install spyder using mamba

The original solved issue, where I got this from:
mamba-org/mamba#1837
