kernel error, everything blockederror in Sagemaths

hi all hello i am going to decide to leave definitively the association jupyter-sagemaths because it has taken me hours and hours without any resolution but in case it is useful for anyone else, i write the description, being as precise as possible

  • the software are : Macos Catalina 10.15.7 SageMath-9-4 installed in the folder : /usr/local/share/jupyter/kernels/, i only have a sagemath_9_2_all. before there was a Sagemaths_9_5 kernel there, i typed : jupyter kernelspec uninstall and it said : Couldn't find kernel spec(s): /usr/local/share/jupyter/kernels/SageMath-9.5/ so i have rm -r the 9.5 kernel and the problem remains the same…

  • the situation is : when i launch SageMaths, it proposes me :

  • terminal : works fine
  • jupyter : returns error : Firefox ne peut établir de connexion avec le serveur à l’adresse localhost:8888. except if i do "jupyter-lab" in the terminal before if so : nothings work (kernel error)

  • what i have done : $ pip install pip-autoremove $ pip-autoremove jupyter -y pip uninstall notebook pip uninstall jupyter_core pip install jupyterlab without any success

  • i have not tried to install via conda because a cuple of months ago it worked very well until this evening where i had to clean my harddrive a bit now, the jupyternotebook says "kernel error" and i can not execute any code any longer i had a long work to prepare this evening… any help welcome ! Vincent

    fine, without conda
