@tesseslol Judging by the log, it looks like there are two installations of Python on your computer:

• one provided by anaconda and installed on the C: drive,
• and the other installed on the D: drive

@tesseslol Thanks for that log. I'll fix the error message. But note that fixing the error message won't fix the issue in your computer.

[n-riesco]

I've fixed the error messages in master. To install IJavascript from master, run:

npm install -g git+https://github.com/n-riesco/ijavascript.git

[tesseslol]

This is the result of ijs command with the version on master:

Error parsing Jupyter version:

@tesseslol What do you get when you run jupyter --version?

[tesseslol]

@n-riesco When i lunch this command an instance of atom is opening. I think there is some problems with hydrogen package for atom.

@tesseslol I still suspect there is a problem with the installation of jupyter. Could you run the following in a Python console?

In [1]: from jupyter_core.version import __version__

In [2]: __version__
Out[2]: '4.3.0'

[n-riesco]

Also, running the following in the Windows prompt may give us more info:

C:\> where jupyter

[tesseslol]

@n-riesco
1° command:

I've just watched the video. It looks like your machine is configured to open python files using Atom. I'm not sure why that happens when you run jupyter from the command line.

Are you affected by this issue?

[n-riesco]

Does the following work?

"C:\Users\Tessari Davide\Anaconda3\Scripts\jupyter.exe" --version

[tesseslol]

@n-riesco yes work

[n-riesco]

Not sure it'll work, but you could try to define a macro before running ijs. Like this:

doskey jupyter=jupyter.exe $*

But this is really just a quick patch. The underlying issue is that jupyter.py is opened by Atom, instead of run by python.exe.

Work !!! thz
