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?

Answer 1

To list packages that are installed on your anaconda machine

conda list

This is to list all packages available for anaconda

conda search

Answer 2

You can just type "conda search" which will give you something like the following.

$ conda search 
Fetching package metadata .........
affine                       2.0.0                    py27_0  defaults
                             2.0.0                    py35_0  defaults
                             2.0.0                    py36_0  defaults
alabaster                    0.7.3                    py27_0  defaults
                             0.7.3                    py34_0  defaults
                             0.7.7                    py27_0  defaults
                             0.7.7                    py34_0  defaults
                             0.7.7                    py35_0  defaults
                             0.7.9                    py27_0  defaults

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

Answer 4

To search for a specific package, use: conda search -f <package_name>. For example, based on the question, to search all versions for "jupyter" package, you'll do: conda search -f jupyter. This will only return information about packages named "jupyter" exactly.

Answer 5

If you know the name of the package you want to install search for all available versions of it. eg. for package pandas you will do the following

conda search pandas

and then install the version you want using

conda install pandas=1.0.2

Answer 6

As an addendum, you can use the output of conda search to fine-tune the version of the package you need installed. E.g. in the list from the 'nasica88', there are three albaster 0.7.7 versions available with with different python versions. If you require e.g. albaster 0.7.7 with python 3.4, you install it as following:

$> conda install albaster=0.7.7=py34_0

So, the second = sign is your friend here.
