Than I have tried to solve this problem by all the tips of The environment is inconsistent, please check the package plan carefully but non of them worked and gave similar error messages like the one bellow.

I have tried:

  • conda clean --all [and then] conda update --all
  • conda update --all [only]
  • conda install
  • conda install anaconda
  • one by one installing the problematic packages

Solution
    1. just uninstall anaconda https://docs.anaconda.com/anaconda/install/uninstall/ with all it's packages than reinstall.
    2. if that did not work than reinstall all other package management tool.: homebrew, miniconda, pip and anaconda.
