ModuleNotFound error.

[hammer]

I created a new environment (env2) and used pip to install KivyCalendar-indicates installed successfully,see below. The application and its associated data base is located in this same environment folder. There has only been python 3.8 installed on this machine.

Where should i start looking to understand why it can not find it?

KivyCalendar is old and probably only supports python2.7 out of the box. See if KivyCalendar3 does any better for you.

Thanks, is kivyMD a better source for widgets like these? All the kivyMBD info looks slick on mobile devices. is it the same on desktops?

Same error after loading KivyCalendar3 even though the file does exist!
Let me share more information that may be relevant in hopes for some direction on a solution.

*I created an environment called env2 and activated it in the home terminal window (as opposed to the VS Debug terminal window- I really do not understand the differences here yet).
* I moved a copy of my application to the env2 folder.
* I used pip to install both kivycalendar3 and kivymd from the home terminal window. NOTE: both these folders DO now show up in env2/lib/python3.8 /site-packages/
*I use Visual Studio debugger
- I opened the application i had pasted into the env2 environment folder
- I noticed that the VS terminal did not show me active in the env2 folder like the home terminal screen did so i ran the 'source bin/activate' to get there.

?? DID I PASTE MY PROGRAM INTO THE WRONG LOCATION maybe??

I do not help that you have installed KivyCalendar3(not use) or KivyMD(what you should),
into the the virtual environment,most also specify what you use in a buildozer.spec file.
Also in this file most Kivy version used and all 3-party modules be.
Look at tutorial eg Convert Python to Android.

Could it be Visual Studio Debug console does not recognize kivyMD? I never could get past the import statement for anything kivyMD in VS without the error. By chance i ran from the terminal and did not get any " no module kivyMD" error.
Anyway thank you- you got me thinking.
