MyBinder stopped working for Repo

Binder mybinder.org ops

My binder stopped working for the repo GitHub - StephanieWehner/IntroQCryptoBook: Jupyter Sheets in the Julia Language for the Book Introduction to Quantum Cryptography

It’s entirely unclear to me why. I recently fixed some typos in the Jupyter Sheets but they all run fine locally. The error message from MyBinder unfortunately does not help me to understand what I should do. Can anyone help? Many thanks!

Without seeing the environment.yml, I suspect `environment.yml` with only `python >=x,<y` fails · Issue #1301 · jupyterhub/repo2docker · GitHub

The nickle fix:

  • don’t pin python at all
    • it’ll get whatever the default is
      • I think python 3.10 today
  • pin to python with - python ==3.11.*

Hello, I am also getting this error and I’ve unpinned all of my dependencies so I don’t think it is related to how python is pinned.

Here is a link to the repository I am trying to launch using binder:

My environment file looks like this:

name: voila-view
# channels priority
# see https://bioconda.github.io/
# conda-forge has highest prioriy
# ---------------------------------
# dev env currently contains
# requirements for both UI and API
channels:
  - defaults
  - conda-forge
dependencies:
  - python
  - jupyterlab
  - voila

Any help with this is much appreciated. Thank you!

It looks there is an issue with using the newest python version 3.11.

After setting python=3.10 in my environment.yml, the environment was installed successfully.
