Why is `conda install jupyter` installing jupyter-lab?

I create a virtual environment using conda and install jupyter (on macOS). I can open JupyterLab using both jupyter-lab and jupyter lab.

The paths to jupyter and jupyter-lab are:

$ where jupyter
/Users/user/anaconda3/envs/test1/bin/jupyter

$ where jupyter-lab
/Users/user/anaconda3/envs/test1/bin/jupyter-lab

Why is jupyter-lab being installed? It seems redundant.

Solution

  • This appears to only affect recent builds in the anaconda (defaults) channel (see files). Narrowly, the "why" is because the Anaconda Inc. developers changed the recipe to require jupyterlab starting with build number 8 (from about 8 months ago). Prior to this it was not included.

    If you want a rationale for why this change was made, then file an Issue on the anaconda-issues repository.

    Note that the Conda Forge version does not install jupyterlab.
