Give a documented dependency install on Linux (ubuntu)

[nirvaan97]

I been trying to install ijavascript on my machine which is running ubuntu 20.04 lts
but , i already have installed jupyter-lab via pip and have snap package for node 16x and npm 8x but still when i installed ijavascript except for the uuid error saying it was deprecated , every thing else went without any error, Except when i opened the jupyter lab and tried to use the node kernel it said that no such kernel, i even installed the jupyter package as so mentioned on the first instruction of the ubuntu installation . but still i was not able to use the package.

so please look into this and be kind enough to give a complete dependency resoled installation Thank you.

one more thing the method you mentioned for the windows i was too not able to installl via that

Sorry about that!

I opened #245 to remind myself, but this documentation really needs more visibility. The solution is hidden in #221 (comment) and the comments of some installation issues.

Basically, iJavascript depends on zeromq (which distributes pre-built binaries for each OS and Node.js version). Unfortunately, zeromq hasn't caught up with the newer versions of Node.js.

Really, I should give more visibility to this issue in the README.

Anyways, for Debian and Ubuntu, the following should do the trick:

sudo apt-get install nodejs npm jupyter libzmq3-dev
npm config set prefix $HOME
npm install -g ijavascript
ijsinstall

In your case, sudo apt-get install libzmq3-dev should be enough, as it sounds like jupyter and node are already installed in your machine.

Sorry to be a bother again but that thing did not help and i don't seem to understand the problem

and again i have

• jupyter 4.6.3-3 all Interactive computing environment (metapackage) /home/nirvaan/.local/bin/jupyter

• nodejs v16.14.0 installed via snap (and even is workable in the terminal as well as vs code "/snap/bin/node"

• npm 8.7.0

• jupyter-lab installed via the pip of the python 3.8 "/home/nirvaan/.local/bin/jupyter-lab"

and now with your suggested package i seem to full fill all the requirement but still its not working

[n-riesco]

That error message is telling us that zeromq didn't find the binary for your installation.

My guess would be that IJavascript needs reinstalling to make sure it builds a binary from source:

$ npm uninstall -g ijavascript
$ npm install -g ijavascript
$ ijsinstall

If that doesn't work either, I'd install a kernelspec with full paths, to rule out using a previous installation of IJavascript:

$ ijsinstall --spec-path=full

[nirvaan97]

sorry to respond this late , but i guess this is not for me as still its giving me the same errors as it was giving me earlier.
Even this thing is not installing over the windows10 and there its giving me ERROR 1 from the npm.
Thanks by the way for responding so quickly.

[n-riesco]

I'd need to know what command is failing and the error messages to be able to help further (the error number doesn't help me enough).

To build from source in Windows, VS is needed. If you're using VS 2022, see #253 . But again, error logs would help.

[nirvaan97]

just to show what a already have installed


these were the errors i got while installing over the window 10

Ubuntu errors

[n-riesco]

In Windows, npm install -g ijavascript fails, because it can't locate an installation of Visual Studio. See here the requirements to build from source.

In Ubuntu, jupyter fails to launch the Ijavascript kernel, because it can't locate the binary for zeromq:

• Did you run npm uninstall -g ijavascript?
• Did you get any errors when you you run npm install -g ijavascript?
• Did you try ijsinstall --spec-path=full?

[nirvaan97]

In Ubuntu, jupyter fails to launch the Ijavascript kernel, because it can't locate the binary for zeromq: How do i solve it cuz i did install it the way you told me earlier

• sudo apt-get install libzmq3-dev

Yeah i did try them but nothing helped.

• Did you run npm uninstall -g ijavascript?
• Did you get any errors when you you run npm install -g ijavascript?
• Did you try ijsinstall --spec-path=full?

[n-riesco]

Just to be clear: after running sudo apt-get install libzmq3-dev, you also need to:

• reinstall IJavascript:

$ npm uninstall -g ijavascript
$ npm install -g ijavascript

• and reinstall the kernelspec

$ ijsinstall

Please, let me know if you get any errors when you run npm install -g ijavascript.

If you get no errors and it's still not working, try to install the kernelspec with full paths:

$ ijsinstall --spec-path=full

If it's still not working, please, could you run the following and post the output here?:

$ jupyter kernelspec list --json
$ which ijsinstall

[nirvaan97]

1. here i installed sudo apt-get install libzmq3-dev and reinstalled the ijsintall
   

2. Please, let me know if you get any errors when you run npm install -g ijavascript.

• the only error i ever got was following
  

3. If you get no errors and it's still not working, try to install the kernelspec with full paths: $ ijsinstall --spec-path=full

• but still got that same no kernel error

4. If it's still not working, please, could you run the following and post the output here?:

$ jupyter kernelspec list --json
$ which ijsinstall

[n-riesco]

Sorry: /home/nirvaan/bin/ijsinstall must be a file link. Could you run ll $(which ijsinstall), please? I want to check that it's using the Ijavascript installation in /home/nirvaan/lib/node_modules/ijavascript.

If it does, I can't explain why you didn't see any errors during npm i -g ijavascript (other than the uuid warning). But you could try to rebuild Ijavascript manually, by doing the following:

$ cd /home/nirvaan/lib/node_modules/ijavascript
$ rm -rf /home/nirvaan/lib/node_modules/ijavascript/node_modules
$ npm i

If after this it isn't working, I'll try to reproduce the issue in a VM, but I can't do it today.

1. Could you run ll $(which ijsinstall), please? I want to check that it's using the Ijavascript installation in /home/nirvaan/lib/node_modules/ijavascript.

• i did not get what you meant by Could you run ll $(which ijsinstall),
• i hope it meant going to the directory so i did that
  
• i also ran which ijsinstall which gave following
  
  owing but that you already know

2. If after this it isn't working, I'll try to reproduce the issue in a VM, but I can't do it today

• no worry you take your time .
  and let me take time to thank you a lot for all the help you are giving,
  really Thanks a lot.
