I know this doesn't tell you much about the problem, and it's probably an environment problem, but I'm new to Linux/Python (switched from Windows/.Net 7 days ago) and wouldn't really know where to start gathering information, let alone diagnosing the error.
The problem was that the database was not configured. Adding the default entry for DATABASE in settings.py and the running python manage.py syncdb fixed it.

I am new to airflow. I created a virtual environment and followed the steps in https://airflow.apache.org/docs/apache-airflow/stable/start.html. In the end I gave "airflow standalone" and got "ValueError: Unable to configure handler 'processor'"

(Background on this error at: https://sqlalche.me/e/14/e3q8)
Is there a way to fix this? I believe this problem is because of some mistake in the initial setup or configuration. Can a more proper fix be found rather than a temporary one.
It seems like the user doesn't have the privilege to write logs under your airflow distribution folder.
Could you try granting write permission to the folder, so that airflow instance can write logs
sudo chmod -R 777 /home/user/airflow_logs
Please change the logs directory accordingly.
Recently I implemented lock.py in my python project for locking threads, using memcached. However I encoutered an error which I have trouble solving. It says that memcache does not containt attribute Client. I am not using Client directly, I believe it's just being called inside the imported modules. I have installed both dogpile.cache==1.1.5 and python-memcached==1.59 using pip. Could someone please help me?
Here is the full error message:

When i got to the stage of 'makemigrations' it didnt run and not i cant use the command 'runserver' either.

I was told that I could use the CS50 API to make things easier, but I am using VS Code on a Windows machine. I also know that the lecturer uses Mac. Does anyone know how to solve my problem? Thanks
-Max
EDIT:After going through the tutorial again from scratch i got the same problem. While looking through the syntax there was an error:
ModuleNotFoundError: No module named 'flights.url'
I went to the location that this was displayed and then realised i had forgotten a 's' in flights.urls. This was possibly not the problem i had in the past but now my code is allowing me to makemigrations.
I am currently trying to figure out how to use netmiko to automate some of my routine work.Such as getting configuration backup, creating vlans etc.I've managed to use it on Aruba and Huawei Switches without problem.But on alcatel switch I'm facing this issue:

Thanks for your help in advance.
It looks like tplink_jetstream.py assumes that a (now removed) helper function is available to it. The simplest fix here would be to go into that file and modify the line containing crypto_utils.bit_length(parameters.q) to read parameters.q.bit_length() instead.
I am getting an error when I am trying to do a
python manage.py syncdb.
The error is as shown below

_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)")
Any idea what could be the reason?
Read your debug messages more careful.
Error is "Can't connect to local MySQL server through socket". U should check your connection params at settings.py
The default path to MySQL socket doesn't work on MacOS X.
This SO question provides a good answer to that problem, along with some handy links for further reading.
