Installation problem - No module named hide_code_html_exporter

[kjkeefe]

I am trying to install hide_code. It is exactly what I've been looking for for my jupyter notebooks. Please let me know what I can do to fix this error!

$ jupyter nbextension install --py hide_code

Looks like hide_code isn't installed. What does pip list show?

[kjkeefe]

I think it is installed. When I do

pip list

, I get the following entry:

hide-code                0.5.5

I am using a Macbook running Mojave. It is running Python 2.7.16 Anaconda.

Hi,

same is happening to me. I can't see the extension because of this error. Any solution?

Thanks!!

[javierrodenas]

Hi,

I have found the solution. With version 0.5.0 it works

pip install hide_code==0.5.0 jupyter nbextension enable hide_code --py jupyter nbextension enable hide_code --py

[kirbs-]

I'll check it out

[kjkeefe]

I tried @javierrodenas 's solution. Although, I changed his second line to:

jupyter nbextension install hide_code --py

This all appeared to work and I was able to launch jupyter-notebook. However, when I opened a notebook or created a brand new one, I got this exception on the console:

[kjkeefe]

By the way, thank you for your work on this! I'm looking forward to having this working on my notebooks.

[javierrodenas]

Hi @kenjkeefe,

I am seeing that you are using python 2.7. It couldn't be adapted for this version but I'm not sure.

Could you update python version? I am using it with python 3.7 and it works perfectly.

Best regards.

I'm not entirely sure any versions after 0.5.2 work with Python 2.7. It was officially deprecated at the end of 2019. Try using 0.5.2 with pip install hide_code==0.5.2 --force-reinstall
