OSError: /usr/lib/libyara.so: cannot open shared object file: No such file or directory

I have some issue trying to run Volatility 3 Framework.
git clone https://github.com/volatilityfoundation/volatility3.git
cd volatility3/
python3 vol.py ../ramdumps/1289.raw windows.pslist.PsList
I got this error traceback:

Someone already had the same error a few years ago but none of the answers worked for me.
I'm using python 3.6.9 and Xubuntu 18.04.6

You have to uninstall yara with pip. Only tara-python must be installed.

Did you install the requirements with
pip3 install -r requirements.txt
?

Could not find Django-eel - pyinstaller+django-eel

I'm using the library Django-eel,which is a library i use alongside Django. After using pyinstaller to create a EXE file, the following error pops up when opening the EXE:
daphne\server.py:11: UserWarning: Something has already installed a non-asyncio Twisted reactor. Attempting to uninstall it; you can fix this warning by importing daphne.server early in your codebase or finding the package that imports Twisted and importing it later on.

So I tried using hidden-imports and add django-eel but that didn't work as well.
Any ideas?

Pyinstaller Matplotlib [Errno 2] No such file or directory: 'C:\\Users\\User\\AppData\\Local\\Temp\\_MEI142562\\matplotlib\\mpl-data\\matplotlibrc'

I want to make a standalone exe with pyinstaller.
If I execute the .exe file I get the following Error:

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\User\\AppData\\Local\\Temp\\_MEI142562\\matplotlib\\mpl-data\\matplotlibrc'
I hope someone can suggest a fix.

I don't know if it's the most correct answer, but I had the exact same problem as you.
For me solved, re-installing the Pyinstaller version develop
pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip

Error: 'dagster.core.types.runtime' is not a package

Installed dagster for the first time in a conda environment and tried to run the airline demo as described here. The following are the steps I followed.
conda env create -n dagster python=3.7
conda activate dagster
pip install dagster dagit
git clone git#github.com/dagster-io/dagster.git
cd dagster/examples
pip install -e '[.full]'
docker-compose up -d
cd dagster_examples/airline_demo
dagit
I then get the following stack trace ending in the 'dagster.core.types.runtime' is not a package message:

ModuleNotFoundError: No module named 'dagster.core.types.runtime.runtime_type'; 'dagster.core.types.runtime' is not a package

Thanks for reporting this issue! After some digging, it seems like this commit was not compatible with the latest release of dagster (at the time) which caused the error.
Re-running this workflow with the most recent dagster master and dependencies should resolve this. Opening an issue here to track a more long-term fix.
More details: In this commit, 'create_string_type' is introduced to both 'examples/dagster_examples/airline_demo/types.py' and 'python_modules/dagster/dagster/core/types/runtime/runtime_type.py'. However, based on the commands pasted in the question and present in the airline demo steps, airline_demo pipeline was running the tip of master (which contained 'create_string_type') with an older dagster package (from the latest release, which did not contain 'create_string_type').

Run installed package from pexpect

I have downloaded pyocd and built it successfully. Now I am able to run the tool from command line from any location. However when try to run it using pexpect it shows following error:

pkg_resources.DistributionNotFound: The 'pyocd==0.14.1.dev277+dirty' distribution was not found and is required by the application
Please help to understand what is wrong and why it works from command line?

The problem was that I tried to spawn pyocd.exe and pexpect was not able to find the package.
I changed the line to python -m pyocd and it just works fine.
I am new in Python and mistakenly thought that exe is compiled code as the other exe files in Windows. However, it is just an instruction to run the package using Python.
