[imb4dm4n]

I have installed yara-python for my server. In the python3 shell, I tried to import yara. It failed with the following messages. If I install yara module, and import yara again. It show that libpcre.so.3 is missing. I google a lot about this problem but can't find any clue.

In addition, there are libpcre.so.2 and libpcre.so.1 on my server.

Which steps did you follow for installing yara-python. The libpcre.so was used in very old versions of YARA, but is not used anymore.

/home/user_name/.local/lib/python3.6/site-packages/yara/init.py that path makes me think you did pip3 install yara which (last time I checked) was not the same as the yara-python module.

/home/user_name/.local/lib/python3.6/site-packages/yara/init.py that path makes me think you did pip3 install yara which (last time I checked) was not the same as the yara-python module. I think I installed the right yara.... $ pip3 list|grep yara yara-python 4.2.0 yara-python-dex 1.0.1

I just install yara-python. If I instlal yara, and import yara, I got this: `[user@vm18 themis]$ python3 Python 3.6.8 (default, Aug 6 2021, 10:05:57) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] on linux Type "help", "copyright", "credits" or "license" for more information.

As @wxsBSD said you have this installed: https://github.com/mjdorma/yara-ctypes. That python module is also called yara, and is colliding with yara-python. You may have both installed, but yara-ctypes is taking precedence.

@plusvic @wxsBSD Thanks a lot. Problem solved! I should look careful when I install this model.

I'm stuck on this too. I've tried building it myself to no avail.
