I have troubles replicating a JupyterLab install on a new PC. It is working fine on my previous one.I am unable to display simple widgets (like a checkbox from ipywidgets or ipyvuetify).I checked that jupyter-widgets is enabled with jupyter labextension list. The results is :
jupyter-vue v1.7.0 enabled okjupyter-vuetify v1.8.4 enabled ok@jupyter-widgets/jupyterlab-manager v5.0.2 enabled ok (python, jupyterlab_widgets)In the notebook, when i try to display a widget, the cell displays a Javascrip error :
