Autosave Error on Windows #44

Closed joonyoo closed 6 years ago

joonyoo commented 6 years ago

Using a windows 7 box, after opening the notebook with nbopen and making a change I get the following notice and error:

image

and "Unexpected error while saving file: Desktop\etc\etc to notebook.ipynb [Errno 2] No such file or directory: 'C\Users\ipynb_checkpoints\username\Desktop\etc\etc\notebook-checkpoint.ipynb

It appears the autosave is placing the ipynb_checkpoints in the wrong location of the path.

That's weird, because I don't think nbopen does anything with the checkpoints folder. Are you opening a file from a checkpoints folder? And is the notebook server already running?

Similar issue, see also https://github.com/jupyter/notebook/issues/2512.

When I open a notebook (from Windows Explorer) within a subdirectory of my home directory (using nbopen), I receive the following: image

I see that the url is the following:

http://localhost:8888/notebooks/Documents%5CUntitled.ipynb

I saw somewhere else that we were supposed to be able to set default program for .ipynb files to be nbopen, but this will open the file in the above url (containing %5C). The notebook is displayed, but saving is not possible, resulting in above error.

Another issue is that sometimes, when I try to open the file, it says that an existing server is already present:

C:\Users\eriha\Documents>nbopen Untitled1.ipynb Using existing server at C:\Users\eriha [W 14:43:14.351 NotebookApp] server_extensions is deprecated, use nbserver_extensions

even though no server is running.

I've just released 0.4.3, which should fix some issues on Windows, but I'm not sure if it fixes all of this. Can you upgrade and try?

erihanse commented 6 years ago

I believe it's fine now. Thanks.

takluyver commented 6 years ago

Thanks

I might have been to fast. Now the kernel won't start with R, but the above error is fixed. It works without using nbopen though.

takluyver commented 6 years ago

How do you launch it when not using nbopen? My best guess would be that there's a difference in the environment when it's launched from a GUI versus launching from a command prompt.

Windows explorer. I ran python -m nbopen.install_win as instructed. Here is some output from nbopen.exe:
