I am currently working on test automation using Python. I was trying to use Allure which, first, requires Pytest. After installing these two module, I proceeded to call:
pytest --alluredir $OutputPath
But got the [WinError 87] parameter not found message. In order to confirm that Allure was not causing the problem I then tried to only invoke Pytest through the Python interpreter from the command line with:
python -m pytest
But still got the same error. Looking online, this error has been happening for a while but I cannot seem to find an answer.
I'm using these versions:
Python-> 3.7.4
Pytest-> 5.2.1
IDE-----> Visual Studio code
OS-----> Windows 7

Apparently Python 3.7.4 does not work with Pytest as stated on this GitHub question. This question is thus considered answered.

I am trying to make an executable of a python 3.10 file using PyInstaller in the command prompt:
python -m PyInstaller --onefile 1.0.py
with "1.0" being my file name. I have done this many times before on the same PC and with the same python version, but for this file it is throwing a "file specified not found" error:

Please could someone let me know how I would solve this or otherwise another method of turning this into an .exe. Thanks
Update:
I have tried uninstalling my python 3.10 and downloading 3.7 instead, as I saw somewhere that PyInstaller is incompatible with 3.8 and above, but this still didn't work for another reason. So I reinstalled 3.10 (effectively at this point I have uninstalled and reinstalled my python and IDE) and I am still getting the same error.

You're getting that error because you, for some reason, have django.contrib.Advisor in your INSTALLED_APPS setting.
Did you maybe mean django.contrib.admin?

See this thread for more info. If you have version 1.4.0 of sqlalchemy uninstall it and install the previous version.
If your code is correct then that should solve the problem.

I would be very grateful if you could please help me, with some of your wisdom :)

This is a problem with python 3.8.5.Try applying this fix https://github.com/odoo/odoo/pull/55305/commits/5baf0f2130b8d27d50aa60b54d68a5fc57b127a0
I have set up Airflow on an AWS EC2 server with Ubuntu 18.04, Python 3.6.9. The DB backend is a 5.7.26 MySQL, I am using a LocalExecutor. The setup is nothing more than:
apt-get install python3 python3-pip python3-venv libmysqlclient-dev
I install Airflow with pip3 install apache-airflow[mysql]==1.10.9, init DB connection, start the webserver and it works both normally and with -D. The scheduler, however, works only when run in the foreground. Trying to run it as a daemon fails with the following trace:

I am trying to set up a server for semi-production purposes, so this is actually a blocker for me. I would be grateful for any advice.
EDIT
I tried using mysql-connector-python==8.0.18 and the scheduler did run as a daemon, but an attempt to open a dag failed with the following trace:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte
The above exception was the direct cause of the following exception:

EDIT 2
What finally did work was using mysqlclient by specifying the SQLAlchemy connection string to begin with mysql+mysqldb. I am not giving this as an answer, because the initial problem persists.
