My binder stopped working for the repo [GitHub - StephanieWehner/IntroQCryptoBook: Jupyter Sheets in the Julia Language for the Book Introduction to Quantum Cryptography](https://github.com/StephanieWehner/IntroQCryptoBook)

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!

Stephanie

Without seeing the `environment.yml`, I suspect [`environment.yml` with only `python \>=x,\<y` fails · Issue #1301 · jupyterhub/repo2docker · GitHub](https://github.com/jupyterhub/repo2docker/issues/1301)

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:

> **[GitHub - ollyhensby/voila-pdf-view-demo: View a dummy PDF file in Voila.](https://github.com/ollyhensby/voila-pdf-view-demo)**
>
> View a dummy PDF file in Voila. . Contribute to ollyhensby/voila-pdf-view-demo development by creating an account on GitHub.

My environment file looks like this:

```auto
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.
