Q:

How to force `conda` to install the latest version of `jupyter`?

This question is motivated by `jupyter notebook` gives error: `"Could not open static file ''"` on macOS
After conda update jupyter, jupyter --version gives jupyter-notebook : 6.0.0
However on https://github.com/jupyter/notebook, clicking Branch: master -> tags I see a 6.0.1 tag.
How can I upgrade to 6.0.1?
> conda install jupyter=6.0.1

PackagesNotFoundError: The following packages are not available from current channels:

  - jupyter=6.0.1

Current channels:

  - https://repo.anaconda.com/pkgs/main/osx-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/osx-64
  - https://repo.anaconda.com/pkgs/r/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

I can't see any candidates on https://anaconda.org
Is this a dead-end?

A:

First, note that the actual package you want to upgrade/install is notebook, not jupyter. The Anaconda channel hasn't released that version of notebook yet. Conda Forge has it, so you can get it with
conda install -c conda-forge notebook

However, just be aware that compatibility between Conda Forge and Anaconda package builds is not guaranteed. Best practice is to create a new env that prioritizes Conda Forge from the start:
conda create -n my_jupyter_env -c conda-forge jupyter

Generally it isn't a good idea to mess with base env, and if you want something other than a default Anaconda install, I recommend starting with Miniconda and leaving base alone (other than the occasional conda upgrade conda).
