I have a program which uses Yagmail and the keyring package to safley store email credentials. When I run this script in atom.io and idle it works.
However, after I packaged it with pyinstaller it is giving me this message:
RuntimeError: No recommended backend was available. Install a recommended 3rd party backend package; or, install the keyrings.alt package if you want to use the non-recommended backends. See https://pypi.org/project/keyring for details.
In my program I have
import keyring
I also have gone and installed keyring.alt
Since i cant add comments, i am adding my inputs in answer block. hope this helps.
I also had similar issue, where i used a keyring module to store passwordin my python script and packaged it using pyinstaller. My script ran perfect when i run it directly. But when i try to run the python exe , i got same error as below
"RuntimeError: No recommended backend was available. Install a recommended 3rd party backend package; or, install the keyrings.alt package if you want to use the non-recommended backends. See https://pypi.org/project/keyring for details."
I googled about this error and found below link (this may not be directly related but there someone gave a workaround). I added the workaround as suggested in the link (you have get which keyring backend you are using as well) and it worked.
Link: https://github.com/jaraco/keyring/issues/359 Code to find which keyring backend you are using
from keyring import get_keyring
get_keyring()
As suggested in the above like you can add the block somewhere in your script and then exe file will run perfectly.
