Issue on Windows OS about ijavascript HOT 20 CLOSED

In the evening, I will try to set up IJavascript on a Windows machine and reproduce this bug.

In the meantime, please, could you post here the output of running:

$ node "C:\Program Files (x86)\nodejs\node_modules\ijavascript\lib\kernel.js"

?

from ijavascript.

Thanks for the quick response.

It looks like you can run the IJavascript kernel from the command line, but not from IPython. I will investigate this further, once I setup IJavascript on a Windows machine.

Hi! I couldn't reproduce the same error message, but I found a bug building the path to the kernel folder. I've just released version 5.0.1 that fixes this bug. Please, could you install IJavascript again and check whether this release fixes the issue for you?

from ijavascript.

I just did a

$ npm install ijavascript

$ ijs

I am getting the same issue as before:

Running outside of ijs, I get

from ijavascript.

The install command is missing -g. Please, try:

$ npm install -g ijavascript

And to confirm that version 5.0.1 is globally installed, try:

$ npm list -g ijavascript

It should show version 5.0.1

from ijavascript.

As indicated above, I did install ijavascript, though not globally.

I just used the exact commands you listed above and confirmed that I am indeed using v5.0.1.

Unfortunately, the problem persists.

The following line in the console output is very odd:

Error: Cannot find module 'C:\Program Files (x86)
odejs
ode_modules\ijavascript\lib\kernel.js'

It looks like the path is not being interpreted correctly. As I mentioned initially, could this be a quoting issue?

from ijavascript.

Oh! So the path is actually printed out broken like that?

Could you check for me if the path in the kernel spec file is also broken?
If you run:

$ ipython locate

It should print the IPython folder. Let's say it prints "C:\Users\breisfeld.ipython". Then, the kernel spec should be located in "C:\Users\breisfeld.ipython\kernels\javascript\kernel.json".

from ijavascript.

This does appear to be broken.

My ipython preferences directory is something like

"C:\Users\USERNAME\AppData\Roaming.ipython"

Within this directory, I do have a "kernels" subdirectory. It contains other kernels I have installed (e.g., julia), but not one for javascript.

I can't find any "...\javascript\kernel.json" on my machine.

from ijavascript.

Just to be clear, when you run ipython locate, what you get is "C:\Users\USERNAME\AppData\Roaming.ipython", isn't it?

from ijavascript.

And one more question: I've noticed you're using IPython 3.1.0, whereas Anaconda 2.1.0 provides IPython 2.2.0. How did you upgrade IPython?

from ijavascript.

$ ipython locate
C:\Users\USERNAME\AppData\Roaming\.ipython

To update ipython, I believe that I downloaded the wheel from Christoph Gohlke's "Unofficial Windows Binaries for Python Extension Packages" site (http://www.lfd.uci.edu/~gohlke/pythonlibs/) and installed that using

pip install ipython‑3.1.0‑py27‑none‑any.whl

from ijavascript.

And when you run ipython --version from the terminal, what do you get 3.1.0 or 2.2.0?

from ijavascript.

$ ipython --version
3.1.0

from ijavascript.

I've just updated IJavascript (v5.0.2). Please, could you install IJavascript again, run the following command and post the output here:

$ ijs --ijs-debug --ijs-install-kernel

?

I hope it'll give me a clue to locate the bug.

from ijavascript.

$ ijs --ijs-debug --ijs-install-kernel
Error: Unrecognised flag '--ijs-install-kernel'

iJavascript Notebook

Usage:

    ijs <options>

The recognised options are:

    --ijs-debug             enable debug log level
    --ijs-help              show this help
    --ijs-working-dir=path  set working directory for Javascript sessions
                            (default = current working directory)

and any other options recognised by the IPython notebook; run:

    ipython notebook --help

for a full list.

from ijavascript.

That output indicates that the IJavascript in your system is version v5.0.0 or earlier.

The easiest way to run IJavascript is when IJavascript has been installed globally:

$ npm install -g ijavascript
$ ijs --ijs-debug --ijs-install-kernel

If you want to install it locally, then running IJavascript requires to include the right path to the local installation:

$ npm install ijavascript
[email protected] ../node_modules/ijavascript
├── [email protected]
├── [email protected]
└── [email protected] ([email protected], [email protected])
$ ../node_modules/.bin/ijs --ijs-debug --ijs-install-kernel

from ijavascript.

Okay. I think I have this working.

I ended up removing my previous ijavascript installations (I had a global and local one) and installed the latest version globally via npm.

Thank you for your help!

from ijavascript.

Does the latest version work for you? Shall I close this bug?

from ijavascript.

Yes and yes.
