Execution failure in a Python 3.9 environment due to resolved networkx being too old #14

Closed ivergara closed 2 years ago

ivergara commented 2 years ago

When installing conda-tree in a Python 3.9 environment, its execution failed. The reason is that the resolved networkx version was 2.3 and that version doesn't support Python 3.9. Manually upgrading to networkx 2.5 solved the issue.

hello, I can't reproduce this with a fresh conda install, I need more details.

  1. try this command to see if it helps: conda install -c conda-forge conda-tree 'networkx>=2.5'
  2. post your conda version and output of the conda install command with the issue

Probably from a fresh install and only installing conda-tree it might not happen. In my case, due to other packages, networkx resolved to version 2.3.

I was just wondering if there was anything doable on your side to force a dependency version 2.5 for networkx when installing in Python 3.9, but I guess that falls more on that package's responsibility.

In any case thanks! I'll close it.

yes I understand, I could try to add 'networkx>=2.5' to conda-tree but then conda might just decide to install a older version of conda-tree without the restriction, just like its happening here with networkx...

I think conda install -c conda-forge conda-tree 'networkx>=2.5' should help tho, I will add this to the readme.

Adding it to the readme might be a good solution. The problem of adding networkx>=2.5 is that that's only needed for Python 3.9 and not to older versions.
