I believe the problem is that you no longer should have `defaults` in the `environment.yml` for a channel, following the example for [Conda environment with environment.yml](https://github.com/binder-examples/conda).  
I just made a fork of the Parcels repo and made that change. Not only does it get past that step and launch a session, the `parcels_tutorial.ipynb` notebook that comes up at launch runs all code cells successfully. Fork is [here](https://github.com/fomightez/Parcels). Try to [launch directly by clicking here](https://mybinder.org/v2/gh/fomightez/Parcels/master?labpath=docs%2Fexamples%2Fparcels_tutorial.ipynb).  
Plus, I had set up an unrelated one using that as a template recently and it worked [here](https://github.com/fomightez/bigdft-binder).

The JupyterLab sample repo listed on [the sample repos page in the Binder documentation](https://mybinder.readthedocs.io/en/latest/examples/sample_repos.html) uses `requirements.txt` and not `environment.yml`. The one I reference above is for use of `environment.yml`.

[The one you reference](https://github.com/jupyterlab/jupyterlab-demo/blob/24a396b12aa0ffbff6360125759585bd13916127/.binder/environment.yml) hasn’t been touched by a human in over a year and perhaps more importantly, is not the one the Binder folks offer as a guide.
