Error or nothing

[daniyalasyed]

When I type this:
python3 -m pip install nbopen
OR
python3 -m nbopen.install_win
... I get nothing.

When I type this: pip install nbopen
... I get this:

Please help.

The error you're seeing is from pip rather than from nbopen. Searching for pip ssl module not available windows found this comment - maybe that's relevant to you?

Alright so I went through that whole thread. A lot of things did not make sense. But then someone suggested to run pip install nbopen in Anaconda prompt instead.

So I did. And I ended up installing nbopen. But when I tried opening the Notebook files, it didn't work.

So I went back to the same anaconda prompt and ran python -m nbopen.install_win. When I did this, the appearance of the Notebook files changed and their file type became "IPython notebook".

I thought this was enough. But when I double-click on the file nothing seems to be happening.

Does it work if you run jupyter notebook in the Anaconda prompt? What about using nbopen from there (python -m nbopen Some_Notebook.ipynb)? It looks like you need to run all commands relating to Python in the Anaconda prompt instead of the normal cmd console.

[daniyalasyed]

The code jupyter notebook opens Jupyter when run in the Anaconda prompt - as expected.

It seems that you're assumption is correct - all commands related to Python need to be run on the Conda Prompt, not cmd.

The command python -m nbopen Some_Notebook.ipynb opens up the link http://localhost:8888/notebooks/Some_Notebook.ipynb when run on Conda Prompt.

But when I run it on cmd, I get:

Traceback (most recent call last):

What should I do now? I want to be able to just double-click on my Notebook files to open them.

I did some more Googling and ended up on
https://stackoverflow.com/questions/52821162/jupyter-notebook-failed-to-load-dll

The person asking the question was facing the same problem I am facing right now. Consequently, I did exactly what the best answer stated. In other words, I added the following paths to my environment variables:
C:\ProgramData\Anaconda3\Library\mingw-w64\bin
C:\ProgramData\Anaconda3\usr\bin
C:\ProgramData\Anaconda3\Library\bin

After this, I was able to open Jupyter from cmd. AND FINALLY when I double-clicked on my notebook file, it opened. I am relieved.

However, I should state that this is not the first time I'll be using nbopen. I just bought a new laptop which is why I had to reinstall it. I never had to add the extra paths in my previous laptop's environment variables.
