I am trying to use cx_freeze to freeze an app that uses Feedparser. The app works perfectly if I launch it from the command line using python. However, when I try to freeze it using cx_freeze, I don't get an error until I try to launch the app. Then I get:
Traceback (most recent call last):

I know sgmllib is no longer used in Python 3, but since I don't get this error when I launch it from the command line it doesn't seem to be a feedparser issue. Any thoughts?
The cx_Freeze developer helped me with this same issue on Github. Here's the thread.

I think this is a Python issue. but I'm running Python3:
python -V shows
Python 3.9.0
I have installed it with homebrew.
What can be the problem?
This is a known issue across Mac, Windows and Linux: https://issuetracker.google.com/170125513.
I'd suggest to use the recommended Python versions mentioned here (3.5 to 3.8).
Also this does not affect only to Cloud SDK but others as well (for example as mentioned here).
Thanks for your answer. Indeed, it works with the version 3.8.6 of python.
I will add some infos if it can help somebody. In order to manage python version, I have used pyenv and installed the version of python I needed.
pyenv install 3.8.6
pyenv global 3.8.6
If you want a quick fix you can add this to your bash profile and restart your terminal:
export CLOUDSDK_PYTHON=python3.8
Worked for me

I have looked around the forums for advice on installing sqlite3 and used
sudo apt-get install sqlite3 libsqlite3-dev
then rebuilt Python but the error still persists.
Can anyone help me out?
