- Django 4.0.4
- Python 3.8.9
I deployed Django App to GAE. But I got "502 Bad Gateway" error. And I checked server logs. That is below.

ImportError: libBLT.2.5.so.8.6: cannot open shared object file: No such file or directory
I'm thinking that GAE instance has no TK or gunicorn is not working. Do anyone know about this kind of problem? Thank you.

CodePudding user response：
Since you have an entrypoint in your app.yaml file which is run via gunicorn, you must explicitly include gunicorn in requirements.txt file

Like you mentioned, the error might be from tkinter, try this:
