I'm working in python in docker, and I need to add the package libLAS.
I usually just add a simple line to my dockerfile, for libLAS it would is:
Run pip install liblas
Docker seems to be able to build the image, but when I run a python script with the line:
import liblas
it gives the error:
Traceback (most recent call last):
File "/src/test.py", line 6, in <module>
import liblas
File "/usr/local/lib/python2.7/dist-packages/liblas/__init__.py", line 2, in <module>

File "/usr/local/lib/python2.7/dist-packages/liblas/core.py", line 158, in <module>
las = ctypes.CDLL(lib_name)

self._handle = _dlopen(self._name, mode)
OSError: liblas_c.so.3: cannot open shared object file: No such file or directory
I don't know what this error message means. Can someone please tell me how I can use liblas in python on docker?
You can add RUN apt-get -y install liblas-c3 in your Dockerfile and then Docker build . to install it.
You are just installing the python bindings. You need also to install liblas itself. If you are using Ubuntu/Debian, try
$ apt-get install liblas-c3

In my Python code I use yara to compile yara rules.
The documentation located at
https://yara.readthedocs.io/en/stable/yarapython.html says that I can use it by importing it like this:
import yara
However when I run the code I get
FileNotFoundError: Could not find module 'C:\Users\bruker\Pycharmprojects\projectx\venv\DLLs\libyara.dll' (or one of its dependencies). Try using the full path with constructor syntax.
I am using a venv python enviroment for this project running in Windows 11.
I have tried the following:
pip install yara
pip install --upgrade --force-reinstall yara
pip install -I yara
pip install --ignore-installed yara
However I still get that the libyara.dll file is missing:
Traceback (most recent call last):

How can I fix the yara dll file missing? I am using Python 3.10.
We have an internal wiki and I want to use pywikibot to get some data from it. Installed it from pip but when I import it I get:
>>> import pywikibot
Traceback (most recent call last):

Looking here https://www.mediawiki.org/wiki/Manual:Pywikibot/Installation#Configure_Pywikibot
I see a reference to pwb.py, but that does not exist in
/usr/local/lib/python3.7/site-packages/pywikibot.
What am I missing here?
Thanks!
Installing pywikibot from pip currently only installs the library part. The pwb.py and related console scripts are not included in the PyPI package. That means that you'll need to create the user-config.py manually or download the scripts in some other way.
I believe most pywikibot users just clone the git repo. The general process would be something like this:
git clone https://github.com/wikimedia/pywikibot.git --depth 1
python3 -m pip install -U setuptools
python3 -m pip install -e pywikibot/
cd pywikibot/
python3 pwb.py generate_family_file.py https://url.to.your/wiki/api.php? mywikiname
python3 pwb.py generate_user_files.py
# follow the prompts
Adding generate_family_file is in active development:
https://gerrit.wikimedia.org/r/c/pywikibot/core/+/634544
The other two script will follow later I guess.
I am trying to get a piece of software called Probemon working and have come up with an error when I try to run it.
As I have both python2 and python3 installed (as per default installation) so I am running the command:

I am not sure what this error is trying to indicate...
Prior to this I have run these commands:
git clone https://github.com/drkjam/netaddr
cd netaddr
sudo python setup.py install
cd
git clone https://github.com/secdev/scapy.git
cd scapy
sudo python setup.py install
to ensure both netaddr and scapy dependencies are installed
To me, the error looks to have a problem with line 11 import netaddr however IF this is the case, I have already installed this, so I am not sure where the problem lies.
I have also tried running sudo python setup.py install for netaddr and scapy as sudo **python2** setup.py install in their respective directories just in case this made any difference which it did not.
Can anyone tell me what what the error is indicating please.
Thanks
I am trying to build documentation in readthedocs for a python module.
In my python module, I import libusb using command import libusb. libusb package requires a libusb-1.0-0 Debian package which is usually installed via sudo apt install libusb-1.0-0.
It seems the readthedocs server doesn't have libusb-1.0-0. Hence I get the following message in readthedocs:
File "/home/docs/checkouts/readthedocs.org/user_builds/strym/envs/latest/lib/python3.7/site-packages/usb1/__init__.py", line 61, in <module>
from . import libusb1
File "/home/docs/checkouts/readthedocs.org/user_builds/strym/envs/latest/lib/python3.7/site-packages/usb1/libusb1.py", line 199, in <module>
libusb = _loadLibrary()
File "/home/docs/checkouts/readthedocs.org/user_builds/strym/envs/latest/lib/python3.7/site-packages/usb1/libusb1.py", line 173, in _loadLibrary
return dll_loader('libusb-1.0' + suffix, **loader_kw)
File "/home/docs/.pyenv/versions/3.7.3/lib/python3.7/ctypes/__init__.py", line 356, in __init__
self._handle = _dlopen(self._name, mode)
OSError: libusb-1.0.so: cannot open shared object file: No such file or directory
As a result, my documentation is not generated.
How should I fix this?
Responding to #eric-wiener
I had given up on that and later I changed my requirements for not to need libusb. However, now that my understanding has become richer, I can suggest doing something like this: Add the following lines to the .travis.yml file:
before_install:
- sudo apt-get -y install libusb-1.0-0-dev
Let me know if it works. If it works then I can mark this as an accepted answer.
I'm trying to use the virtualenvwrapper to make a python 3 based virtualenv. However,I'm when I pass the optional interpreter argument, I'm seeing this error. I'm running Ubuntu 15.04. I tried reinstalling virtualenv and virtualenvwrapper without success. Thanks for all your help!

I come across same issue, but after I downgrade virtualenv to 12.0.2, this problem disappears.
This is sort of a workaround for now.
Create a virtualenv using pyvenv.
# install pyvenv on Ubuntu
sudo apt-get install python3-venv
To minimize disruption in your normal workflow, pass a destination directory that is the same as the one used by virtualenvwrapper Like so,
pyvenv example ~/.virtualenvs/example
This is automatically working with workon and cdproject commands. I don't use much else that is provided by virtualenvwrapper
Hope this helps.
You can upgrade to the most recent version of virtualenv, with:
sudo pip install --upgrade https://github.com/pypa/virtualenv/archive/master.zip
virtualenv --version
# Returns 15.2.0.dev0 when I ran it
The following command then works:
mkvirtualenv scriptcutter --python=/usr/bin/python3
Apparently, the develop branch was dropped, so the URL with "develop" will no longer work. My answer was based off of #pjotr_dolphin's comment, with the URL updated.
