There seems to be a problem with a lot of the demos of binder and Jupyter lab.
Some examples that don’t work:
- The JupterLab binder example: https://github.com/binder-examples/jupyterlab
- The Jupyter extension example: https://github.com/binder-examples/jupyter-extension
- My own binders that were previously working also fail: https://github.com/0Hughman0/unscrabbler
The examples that fail all run postBuild operations that build extensions. (https://github.com/jupyterlab/jupyterlab-demo does work)
I think it might be related to running out of memory when building extensions, as described here:
but it’s hard to tell because you can’t access the build log file in binder.
