Azure-functions-core-tools: Can't install pycurl to python function

[hihorika]

I added pycurl to requirements.txt as following.

requirements.txt

pycurl==7.43.0

When executing func command in order to deploy python function, I got following error.

$ func azure functionapp publish <function_app_name> --build-native-deps
Getting site publishing info...
Running 'docker pull mcr.microsoft.com/azure-functions/python:2.0.12285'...done
Running 'docker run --rm -d mcr.microsoft.com/azure-functions/python:2.0.12285'...done
Running 'docker exec -t 6dc22c mkdir -p /home/site/wwwroot/'..done

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-9bu40h2p/pycurl/

Could you please help me to install pycurl?
Isn't pycurl supoorted?

try adding --additional-packages "libcurl4-openssl-dev libssl-dev" to your command.
