How to list package versions available with conda

Question

IS there a way to see what package versions are available with conda? I am getting an error with jupyter but it was working before. Something like yolk?

To trim down the long and slowly loading conda search output to just the (latest) version(s) appropriate for your environment, you can use MatchSpec filters, as documented here in conda Github repo

For example:

$ conda search "conda-forge::*[name=scikit-learn, subdir=linux-64, build=*py37*]" | tail -n5
scikit-learn                  0.21.2  py37h627018c_0  conda-forge
scikit-learn                  0.21.2  py37hcdab131_1  conda-forge
scikit-learn                  0.21.3  py37hcdab131_0  conda-forge
scikit-learn                    0.22  py37hcdab131_0  conda-forge
scikit-learn                    0.22  py37hcdab131_1  conda-forge

Note that the most recent version is placed at the bottom of the list (they are sorted in ascending chronological order), so it can be found using tail -n1, e.g.:

$ conda search "conda-forge::*[name=scikit-learn, subdir=linux-64, build=*py38*]" | tail -n1 | awk {'print $2'}
$ 0.23.2

Cautions:

• using version for narrowing down major and/or minor version is risky, because version=1.*.* would miss versions such as 1.1 or 1,

• setting architecture (using subdir key) to linux-64 can miss some useful linux 64-bit packages, if they are stored in the noarch folder instead of linux-64
