This is driving me crazy! Any help you can provide will be most welcome!
I have a python3/sqlite application (running in a virtual environment) that is working fine on debian. I need to install it on freebsd (running in a virtual environment). I have installed python3 and sqlite (I can open a .sqlite file from the command line).
When I try to run the python script, I get the following error:

You have to install py-sqlite3 which is the "Standard Python binding to the SQLite3 library"
Install From Ports:
cd /usr/ports/databases/py-sqlite3/ && make install clean
Install From pkg:
pkg install databases/py-sqlite3
Basically, it looks like the standard Python bindings for SQLite is a separate package on FreeBSD (perhaps, on all *nix/*BSD). So, in general, there are three components, which you need, Python, SQLite (this one may not be actually necessary for Python) AND the standard Python bindings for SQLite. I have not worked with FreeBSD, but based on Googling, have you tried installing this https://pkgs.org/download/py39-sqlite3 maybe?

I am trying to run python3 with ROS. By default ROS melodic is installed with python2.7.
Hence I have installed the python3 using following instructions:
https://dkqhzm2.tistory.com/entry/ImportError-dynamic-module-does-not-define-module-export-function-PyInitcvbridgeboost-in-Xavier-AGX
where I have cloned the cv_bridge src from the following git: which is called vision_opencv
https://github.com/mikejmills/vision_opencv
I also put in my scripts as
#!/usr/bin/env python3
So that it complies in python3 when I did catkin_make
The following error is the trouble with this package:

Not sure what to do.
If I compile only with python2.7 instead of python3 I get error as:

Can someone tell me how to tackle this problem?
You’re trying to use Python2.x code with Python3, which doesn’t work. If you want to use Python3 with ROS you shouldn’t be using Melodic, since it targets 2.x. You can get it to sort of work with Python3, but it’s still not a great idea.
If you want Python3 you should be using the Noetic distro.
I am receiving the following error when I try to run a django shell. I am on a Mac though and everything that I can find says that this is associated with Windows and that winreg should be installed by default. Suggestions as to what I should be looking at?

Between when I had a working env and the env producing the error I made a lot of changes to a script that I was working on including installing packages and adding modules.
When I tried to run the script I received the error above.
In the comments, Iain asked for the command I was running and then the contents of the script. Out of all the things I was looking at -- I ignored this, because was certain it was something I installed, not the file I was working on.
At the top of the file, I found this line in the imports:
from winreg import FlushKey
^^ My best guess is that this was accidentally added while I was quickly moving across the keyboard too quickly and I didn't noticed and pressed some sort of key combo that added it.
This is a first. 🫣
I've tried to create an executable of my python script with pyinstaller, but it's not working.
If I run the exe file from terminal, I get these errors:

I installed pyinstaller using pip inside the virtual environment of the project.
I would appreciate any help.
Thank you in advance.
Seems you have missing modules, that weren't found by PyInstaller analysis hooks.
Try to rebuild your application with --hidden-import=docx2pdf option.
I am currently using spyder via anaconda with python 3.8.5 on windows 10 and I am trying to use the pyzbar package to make a barcode reader. When I try to run the script I get this error message when trying to run from pyzbar.pyzbar import decode and from pyzbar import pyzbar:

When trying to run just import pyzbar it will compile, but it will not be able to access any of the function. When I try I get this message:
Traceback (most recent call last):
File "<ipython-input-3-26272af93b8a>", line 1, in <module>
pyzbar.pyzbar.decode()
AttributeError: module 'pyzbar' has no attribute 'pyzbar'
I have looked up the documentation for pyzbar on github which states "The zbar DLLs are included with the Windows Python wheels", but have not found this anywhere. The closest to "Windows Python wheels" I have found is the wheel package which does not contain any information about pyzbar.
Any advice on how to fix this?
Visit https://pypi.org/project/pyzbar/#files to download pyzbar-0.1.8-py2.py3-none-win_amd64.whl.
You can find all the DLL files inside the wheel package.
I have just encountered this problem.
If your OS & python are x64 version, it's just because of lack of vc 2013 x64 runtime.
You can find Visual C++ Redistributable Packages for Visual Studio 2013 here
download & install.
I was facing similar issue just installed Visual
C++ 64 bit version on my computer and restarted. Choose between vcredist_x86.exe or vcredist_x64.exe based on your machine.

I am unable to import "eml_parser" module in Python.
I am running Windows 10, Python37 and Anaconda 5.3 (all 64 bit)
The installation docs are at this link: https://pypi.org/project/eml-parser/
I did find the following suggestion from https://github.com/pymedusa/Medusa/issues/1843 but I have not tried it yet. To update the init file as suggested requires administrative rights and I wasn't exactly sure how to open the file as an administrator and save it that way. It seem to make more sense to ask the question before getting too far into editing files. Note line 362 in the quote below would be the equivalent to line 356 on my error message.
Suggestion from https://github.com/pymedusa/Medusa/issues/1843
"If you are using a special version of Python [like Anaconda] and you can't fix it. Navigate to line 362 of lib/ctypes/init.py and change it to:
self._handle = _dlopen(str(self._name), mode)"
From Command Prompt, I get the following error message:
>>> import eml_parser
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\Python37\lib\site-packages\eml_parser\__init__.py", line 8, in <module>

File "C:\Program Files\Python37\lib\ctypes\__init__.py", line 356, in __init__
self._handle = _dlopen(self._name, mode)
TypeError: LoadLibrary() argument 1 must be str, not None
Im not sure how it fixes this but I tried
pip install python-magic
pip install eml_parser
And got this working on Windows 10
