Running 'jupyter notebook --kernel=powershell ' results in a 'jupyter' is not recognized error

[AncientSwordRage]

I ran the command in the README:

PS D:\jupyter-powershell> ./install-kernel.ps1
Install kernel in ~\AppData\Roaming\jupyter\kernels\powershell

    Directory: C:\Users\<user name>\AppData\Roaming\jupyter\kernels

d-----        19-Feb-17  08:20 AM                powershell
Run 'jupyter kernelspec list' to list all available kernels

I'm not sure what other step are needed, but when I run the command to run it I get this error.

PS D:\jupyter-powershell> jupyter notebook --kernel=powershell

Is Jupyter in your path? It isn't on my system so I launch notebooks from within the jupyter directory

yes, @Djarid is right. The error message is generic error when command could not be found. Please, follow jupyter install guide for install and setup steps.

Unless Jupyter has changed since this, the command will also fail because you can't specify a kernel for a notebook, only for a console or qtconsole.

I'm going to close it as it seems to be ever resolved or too old anyway.
