Python function terminated unexpectedly

woodr2011 · 10-31-2019, 12:55 PM

I am running the most current update of Calibre 4.2 x64 on Windows 10 Pro and am suddenly having the following error popup when trying to open any book other than a PDF (which I open in Adobe):

Python function terminated unexpectedly
[Errno 2] No such file or directory: 'C:\\Users\\Ryan Wood\\imgsrc\\srv\\generate.py' (Error Code: 1)

Below is the debug log file:

Any help would be appreciated as I am ready to pull my hair out!

You are running from source, see https://www.mobileread.com/forums/sh...d.php?t=324376

Hi Kovid,

Thank you for your reply. I am indeed running from source and I have not had any trouble doing so for several years now; however, I am interested in running the app normally. Could you give me the procedure? I neglected to make a record of it, unfortunately. I remember it as being quite a simple process.

Thank you again,

Ryan

My apologies. I managed to find the procedure for deactivating the run from source process. Thankfully, I have preserved virtually all of my emails since 2011!

If you want to run calibre "normally," you should be able to just unset the CALIBRE_DEVELOP_FROM environment variable.

Yes, I deleted the variable. I had been running Calibre from source since 2015, so my memories of the process were scant. Has the program undergone structural changes in the interim that prevent scripts from running as before? Thank you for replying.

What does the script do?

The script renamed certain menu buttons and drop down options to make Calibre look more like a general file organization utility. "Add Books" became "Add Items," for example. It worked flawlessly until the latest Calibre update, which created a Python error when trying to open all of my ebooks. I was happy to sacrifice the script for a fully functional Calibre!

you just need to update the source checkout and it will continue to work.

How would I update the source checkout exactly? Forgive my programming puerility.

kovidgoyal · 11-02-2019, 09:54 PM

Run

git pull

in the directory where you checked out the calibre source code

https://manual.calibre-ebook.com/develop.html

I would need step-by-step directions if you are up for it.
