When trying to run django-celery with beat scheduler:
bin/django celeryd -B --settings=app.development --loglevel=INFO
I got this exception:

AttributeError: 'module' object has no attribute 'open'
My own investigation led me to discovering that the anydbm python module found in
/usr/lib/python2.6/anydbm.py
is an empty file. But the python2.6.5 doc says there is an
anydbm.open(filename[, flag[, mode]])
method.
Am I missing something? I think the anydbm [ubuntu] python module is broken.
I'm using:
Ubuntu 10.04
Python 2.6.5
django-celery 2.1.1
celery installed with buildout
If /usr/lib/python2.6/anydbm.py is an empty file for you, then yes, your installation is broken. /usr/lib/python2.6/anydbm.py is the correct file, with contents, on my Ubuntu 10.04 system, with python2.6_2.6.5-1ubuntu6 installed. You'll want to make sure you have the latest package installed, and possibly reinstall it.

I'm deploying a django app made with django channels using nginx, gunicorn and daphne. During deployment when I run python manage.py makemigrations, I get the following error. Could it be because the python version on my local machine was 3.7 and on remote ubuntu server is 3.5?

The error is beacause of asgiref package that uses asyncio.coroutines._is_coroutine attribute since version 3.2.2.
You can install asgiref 3.2.1 and this problem doesn't happen.
pip install asgiref==3.2.1
I moved my python project from a native Linux installation to Windows and I tried to run pipenv custom scripts through WSL 2 on Windows 10 using pipenv run my_script.
Although the same command works in a native Ubuntu installation, on WSL 2 (Ubuntu 20.04) I get an Attribute error in the shlex module regarding the instream object not having attribute read.
My [scripts] section in the Pipfile looks like this, but I've also tried running python scripts (instead of shell ones) and the error can be reproduced with any custom script.
[scripts]
build = "bash ./scripts/main.sh -b"
analyze = "bash ./scripts/main.sh -a"
I've also tried to update the pipenv package but looks like I'm running the latest version (11.9.0, pipenv-2020.6.2).
My code doesn't seem to run at all since I get an error before the arguments are passed to the custom script. This is the stacktrace I get from running the command:

Any ideas?
Check the shared memory parameter, kern.sysv.shmseg on your linux system and set it right by increasing it.
To view the shared memory parameters, use:
sysctl -A | grep shm
To update that parameters, edit file:
sudo nano /etc/sysctl.conf
Refer to this SO answer for more information.
I am trying to use the google appengine python SKD from my ubuntu lucid. I have already compiled python2.5. But when I execute any "dev_appserver.py" command with it I get the following error:

I have checked the urllib2 moduls of python2.6 and python2.5 but there was no difference in the models defination and HTTPSHandelr is there in python2.5 too. So I guess it is some other sort of error.
I tried to run with the default python2.6 too but then I get the following error:

Update
Problem with python2.6 solved.
I had configured my apache server for a django deployment on the 8080 and 80 port some time earlier.
But there is still same error with python2.5 isntallation.
Solved the issue...just needed to build all dependencies of python using:
apt-get build-dep python
python compiles with no error even when all the dependencies are not installed. It just skips the modules which require them and builds python.
Solution for missing HTTPSHandler:
Before you build python 2.5 from source you need to enable ssl-socket by editing Modules/Setup.dist (more info here http://paltman.com/2007/nov/15/getting-ssl-support-in-python-251/)
The method described in this post worked perfectly for me (Ubuntu 11.10).
