Not working on Windows 10 for spyder-notebook-0.3.1

[HYChou0515]

This is all about version 0.1 of the plugin, we never managed to reproduce it and we have just released version 0.3, so I am closing this issue. If anybody encounters the same problem with version 0.3, please open a new issue so that we can get to the bottom of it.

Hi, I am now facing a similar issue of this 2017 issue. After I start spyder with spyder-notebok plugin installed, it says

The Jupyter Notebook server failed to start or it is taking too much time to do it. Please start it in a system terminal with the command 'jupyter notebook' to check for errors.

Also, when I switch to Notebook pane, the untitled0 is blank and cannot be edited.

I can run jupyter notebook but many of my ports are in use, but jupyter notebook can still find an unoccupied port (8977) and lunched successfully. I've also tried to modify the default port of jupyter notebook to 8977 so it can save time try unused port one after one. Because I know spyder notebook will wait 25 seconds at most.

I've also tried open jupyter notebook in another cmd but didn't help.

spyder-notebook is my first spyder plugin and no other plugin is installed.

I'm using pipenv, every packages are installed by pip.

Thanks for your report. Can you please go to the Options menu (hamburger icon with three horizontal lines) in the notebook pane and click on "Server info"? That should show any error messages from the server. Let me know what you find.

If you don't know where the Options menu is, look at our Quickstart guide and click "Next" until you are at step 4.

The state is timeout and other than that nothing is shown.

[jitseniesen]

Thanks. Unfortunately, that does not really help me to figure out what is going wrong. Perhaps the notebook server is not installed correctly. Did you upgrade spyder-notebook, or is this the first time that you installed it?

I think I will have to install the exact same versions as you with pip on Windows and see whether it works for me.

[HYChou0515]

Yes, I installed it on a new machine.
