在 AWS 上部署 Django 网站时出现 SQLite 错误

Question

I'm neewbie here and in programming, so please have some mercy:D I'm making my first Django project with Maximilian Course. I have made Django blog. I walked through few errors when deploy, but now i have encountered this error after deploy and trying to visit my website on AWS:

Django - deterministic=True requires SQLite 3.8.3 or higher upon running python manage.py runserver

but on debbuging page there is something more: In template /var/app/current/blog/templates/blog/index.html, error at l

and in line 25 this is bolded:

{% url 'single_post' slug=all_posts.0.slug %}

all_post is a context variable which is of queryset type. Is something wrong with this line? On local machine everything works

So I found this solution:

Django - deterministic=True requires SQLite 3.8.3 or higher upon running python manage.py runserver

So i understand it like this:

1. In ubuntu terminal i type: sudo apt install python3.10-venv to install envirement

2. Then in my Django project in Visual Studio i type python3 -m venv django_my_site to create virtual env

3. Now i click "+" to open this env and type pip3 install pysqlite3 and pip3 install pysqlite3-binary

4. After that i type python3 -m pip freeze > requirements.txt

and i get requirements.txt file which looks like that:

asgiref==3.6.0
Django==4.1.4
Pillow==9.3.0
pysqlite3==0.5.0
pysqlite3-binary==0.5.0
sqlparse==0.4.3

5. I have added also 3 lines in settings.py:

    __import__('pysqlite3') import sys sys.modules['sqlite3'] = sys.modules.pop('pysqlite3') DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': BASE_DIR / 'db.sqlite3', } }

6. After that i pack once more all necessary folders and files of the project.

7. In AWS in application versions I upload zip once more and deploy.

8. I rebooted instances and server status is healthy, but still the error with sqlite occure.

Some interesting parts of log file:
