By mistake I deleted and environment, so I created a new one. And I installed jupyther again but when I start it I have the following error:

tried this: t is safe to ignore this error. If you do want to solve it, try running the command "conda install nodejs" and then running Jupyter again. I am a little surprised this happened on one machine and not on the other. I don't know why that would happen. But it didn't work? What can I do? -- You received this message because you are subscribed to the Google Groups "Project Jupyter" group.
