JupyterLab extensions

Hi folks,

I appreciate the great community here. I am installing some extensions for jupyterlab. However, the build process failed. Below is the log file. Any thoughts are well appreciated!

Unless you really need to, you should try to:

  • be running jupyterlab>=3
    • if you can’t control it, that’s one thing, but it’s really much easier for us to help
  • be using only pre-built extensions
    • these are handled by pip install or conda install, and don’t require nodejs to rebuild
    • basically you can check with jupyter labextension list and it will tell you if a rebuild is required
      • if it isn’t… don’t!

So to try again, i recommend:

  • build an environment.yml of all the stuff you need
  • try to conda env update it
  • see if that “just works”
