I'm trying to run this code:
import subprocess
def install_curl():
result = subprocess.check_output(['command', '-v', 'dnf']) #
if not result:
print("You should Install curl")
else:
result = subprocess.check_output(['command', '-v', 'apt'])
print(result)
install_curl()
Then I'm getting this error:
Traceback (most recent call last):

Do you have any idea on how to run this "command" in order to check which package manager is installed in the Operating System?

I've not been able to find anything in the docs about this yet.
I'm running fabric2==2.7.1, invoke==1.6.0, and paramiko==2.8.0 on NixOS stable 22.11.
Invoke currently defaults to /bin/bash, which is a known issue, since operating systems like Alpine and NixOS don't have that path. Fortunately we can specify a command in $PATH rather than manually looking it up, so adding the following to the Connection call does the trick: config=invoke.Config(overrides={"shell": "bash"}).
I hope you're doing well.
I am trying to follow the Pixiedust installation as laid out on the official github (https://pixiedust.github.io/pixiedust/install.html), and install it in windows 10 (64 bit).
when I try to execute instruction “jupyter pixiedust install” I get this error as “OSError: [WinError 193] %1 is not a valid Win32 application”. Let me say this too I was installed Spark (2.4.7) before. I will be very grateful if you help me.

It looks like your jupyter notebook could be trying to use a python enviroment that has been moved or deleted.
Try this in cmd or anaconda:
python -m ipykernel install --user

Note that before installing Anaconda 3, I uninstalled Anaconda 2 (with Python 2.7).
How can I fix this?
Finally I found a solution in the web :
I had to execute the following command :
python -m ipykernel install --user
