5.3.3 seems to be broken

I get this:

ModuleNotFoundError: No module named 'win32api'

There is no such package in Conda land. (at least not according to https://anaconda.org/search

My create command was: conda create -n test23 python=3.6.8 ipython ipykernel pandas

[lramey]

conda install pywin32

fixed the virtual env and jupyter is working again. Looks like a blown dependency file in the 5.3.3 release.

Thanks for the update. I believe @minrk addressed this earlier today: https://github.com/conda-forge/jupyter_client-feedstock/pull/30. Not sure how long things take to surface.

5.3.2 and 5.3.3 are broken. I've run pip install jupyter-client==5.3.1 to fix it.

Reproduce the problem: Have a clean install of Anaconda 2019.07

`Write-Host "Updating Anaconda ..." conda update --all --yes

Write-Host "Updating pip ..." python -m pip install --upgrade pip

Write-Host "Updating python packages ..." pip list | ForEach-Object { pip install --upgrade $_.Split()[0] }

Write-Host "Cleaning Anaconda ..." conda clean --all --yes

jupyter notebook`

Start a new Python 3 Notebook and you get a Kernel error

Updating to conda-forge/win-64::jupyter_client-5.3.3-py37_1 manually fixed this for me.

conda install jupyterlab left me with conda-forge/noarch::jupyter_client-5.3.3-py_0
