Hello

I’m using Python/Quasar on Radsystem 8.1.8. I’m having problems installing Python.  
With Python 3.11 and 3.8 it gives me the same error.

Traceback (most recent call last):  
File “run.py”, line 1, in   
from app import app  
File “C:\ProyectosFinales\st0-py-qua\python-flask-api\app\__init_\_.py”, line 19, in   
db = SQLAlchemy(app) # init database  
File “C:\ProyectosFinales\st0-py-qua\python-flask-api\venv\lib\site-packages\flask\_sqlalchemy\__init_\_.py”, line 758, in **init**  
_include\_sqlalchemy(self, query\_class)  
File "C:\ProyectosFinales\st0-py-qua\python-flask-api\venv\lib\site-packages\flask\_sqlalchemy\_init_.py", line 112, in \_include\_sqlalchemy  
for key in module. **all** :  
AttributeError: module ‘sqlalchemy’ has no attribute ‘ **all** ’

(venv) C:\ProyectosFinales\st0-py-qua\python-flask-api\>

What could be the problem?

Thanks
