Graah, as with jupyter/jupyter_client#615, we want to unpin jed, but only on py3.7+...

[bollwyvl]

Rad! While a useful feature, I still dislike how much space it takes up in the toolbar, but it's one less thing to do.

So we have a pip check failing. Unpinning jedi solves part of the issue (with pyls), but there is still:

autopep8 1.5.6 has requirement pycodestyle>=2.7.0, but you have pycodestyle 2.6.0.

Edit: after pinning pycodestyle and flake8 to modern versions:

Problem: package flake8-3.9.0-pyhd8ed1ab_0 requires pyflakes >=2.3.0,<2.4.0, but none of the providers can be installed

so now it seems pyflakes has an issue on conda...

Though pyflakes 2.3 seems to be on conda-forge: https://github.com/conda-forge/pyflakes-feedstock ...

[bollwyvl]

So... we're not getting very helpful feedback, but I think what we're probably seeing is getting a partial solved for a pyls that is so old it (wrongly) doesn't have a jedi pin. On 3.6, this is pulling in the three year old 0.11.1:

python-language-server    0.11.1                   py36_0    conda-forge

So I don't think we can really unpin jedi until python-ls has a release...

Merging should solve #598.
