Cortex Analysers fails : No module named 'requests'

Request Type

Bug

Work Environment

(replace with N/A if not applicable)

Description

Most of the Analysers are failed to run with the following error messages.
Traceback (most recent call last): File "/xxx/Cortex-Analyzers/analyzers/OTXQuery/otxquery.py", line 4, in import requestsModuleNotFoundError: No module named 'requests'

Traceback (most recent call last): File "/opt/Cortex-Analyzers/analyzers/Abuse_Finder/abusefinder.py", line 9, in from abuse_finder import domain_abuse, ip_abuse, \ModuleNotFoundError: No module named 'abuse_finder'

Installed both Python2.7 and Python 3.6. When I tried to install dependencies manually, it shows that requirements are already satisfied.

When we upgrade the pip version python 27 breaks.

Sample error log
ImportError: /opt/rh/python27/root/usr/lib64/python2.7/lib-dynload/_io.so: undefined symbol: _PyErr_ReplaceException

Start with analyzers/OTXQuery/otxquery.py and analyzers/Abuse_Finder/abusefinder.py, then reproduce the missing-module errors in the reported Cortex 3.1.0-1 and RedHat/Python environment. Check how analyzer dependencies are installed and verify that the affected analyzers import successfully without breaking the supported Python runtime.
