ERROR: No matching distribution found for pycurl==7.43.0.6
Kindly help.
The source of the error is not related to Python or the package pycurl. It was due to the missing libcurl-devel on RHEL.
The error message/trackback did not mention this clearly.
In RHEL 8, I installed the library using sudo dnf install libcurl-devel.
Later, pip install pycurl==7.43.0.6 solved the issue.
