how do I update pandas library using conda in mac os?

问题

I installed anaconda in my Mac and it shows pandas version as 1.0.5. (using conda list )

I want to upgrade my pandas version. How can I do it using conda commands?

I tried conda update pandas but it shows me this

conda update pandas
Collecting package metadata (current_repodata.json): done

Updating pandas is constricted by 

anaconda -> requires pandas==1.0.5=py38h959d312_0

If you are sure you want an update of your package either try `conda update --all` or install a specific version of the package you want using `conda install <pkg>=<version>`

done

# All requested packages already installed.

Apparentely the conda channel has net yet updated the default to the latest pandas version which is 1.1.0, so we have specify the version:

conda install -c conda-forge pandas==1.1.0

I had the same problems as you. This was my sequence of commands that was finally successful. It's not ideal to update everything, but it worked. Save this idea for a last ditch effort.

conda deactivate
conda update --all
