zmq.dll problem

[snowzone5]

I hope this saves a people a lot of time on Windows

I'm very new to nim, but not that new to VScode or Jupyter Notebooks.

nimble install jupyternim -y got me about 99.99% of the way.

The problem was that zmq.dll couldn't be found. Digging in I found the zmq.dll wasn't compiled:

Installing zmq@>= 1.2.1 & < 1.3.0
Downloading https://github.com/nim-lang/nim-zmq using git
 Verifying dependencies for zmq@1.2.1
Installing zmq@1.2.1
  Success: zmq installed successfully.

Yeah, no.

I looked for a zmq.dll to download, found https://www.dll-files.com/libzmq.dll.html, but that was the 64bit version.

Found https://www.dll4free.com/libzmq.dll.html, scanned it for bad stuff, renamed it to zmq.dll and put it in the same folder as jupyternim.exe

Now it works in Jupyter Notebooks (Ananaconda version, and VScode)

Hey! Thanks for the report.
Yeah, the nim-zmq package doesn't compile zmq, it's just to interface with the dll. Usually if you already have a jupyter installation, you should have that in path, otherwise you need to add it yourself. I mention it in the readme, but I'll see if I can find a good source for windows and link to it there to make this clearer.
There should be some error like here:

jupyternim/src/jupyternim.nim

Line 77 in 400ec5d

echo "[Jupyternim] WARNING: No zmq library could be found, please install it"

did you have that? Did it just crash?

Glad you got it sorted!

The only error was: could not load: (lib|)zmq.dll

No crashing though.

Could be I missed that part of the readme :)

This was the first package nim package I've installled that didn't work.

I have two Jupyter installs, one that comes with Anaconda Python, and the other is an extension for VSCode, neither one of them installed the zmq.dll

The second link I posted has the version that worked, I just thought I would help out anyone else who ran into the same issue. :)

Sorry, missed the notification.
Interesting, I also have one jupyter install from miniconda and one from pip, both had the dll. Maybe yours didn't get added to path, so nim-zmq can't find them. I'll see if I can find a more reliable way to check it at installation time and also improve the error message.
Thanks for reporting this!
