Error in opening jupyter notebook

whenever i try to run jupyter notebook it shows me this following message
‘jupyter’ is not recognized as an internal or external command,
operable program or batch file.
I have added all the path to environment variables still this issue prevails

This is a forum for the conda package and environment management system, so your question is only relevant if you’re trying to use jupyter in a conda environment. From your problem description this would seem not to be the case, as when a conda environment is activated, all relevant paths are set automatically.

Under any circumstances you’re not providing enough information for anyone to help you with this problem. For example, how did you install jupyter?
