Build #2 of Clojupyter v0.2.3 uploaded to Anaconda Cloud The new builds include a fix to https://github.com/clojupyter/clojupyter/issues/104 (Clojupyter Jupyter kernelspec is not installed in non-base conda environment). New users will simply get the new versions when doing conda install -c simplect clojupyter. If you have already conda-installed the existing version you can do conda update -c simplect clojupyter.
