Module 'pyrfc' has no attribute Connection

[Menghetz]

Describe the bug I'm trying to implement pyrfc in my python project, but after the installations of the library, I can't call the connection through import.

To Reproduce python -m venv venv .\venv\Scripts\activate pip install pyrfc

Create a file call main.py import pyrfc conn = Connection(ashost='10.0.0.1', sysnr='00', client='100', user='me', passwd='secret') Screenshots

Environment

• OS: Windows 10 Enterprise
• Running in docker? NO
• PyRFC version : 3.3.1

Additional context Add any other context about the problem here.

Do you have a file called pyrfc.py in your project root?

Is SAPNWRFC_HOME set correctly?

What does the following print?

import pyrfc
import sys
import os
print(1, os.environ.get('SAPNWRFC_HOME'))
print(2, sys.modules['pyrfc'].__file__)
print(3, pyrfc.__version__)

I have a simmilar problem.

I reproduced the error with the Dockerfile: redhat.ubi8.Dockerfile

# Example usage: https://sap.github.io/PyRFC/intro.html#example-usage

• Build the docker image: docker build -t pyrfc:redhat.ubi8 -f redhat.ubi8.Dockerfile .
• Run a docker container: docker run -it --rm --name pyrfc_on_redhat pyrfc:redhat.ubi8 /bin/bash
• Run python inside the docker container: python3
• Import pyrfc library: from pyrfc import *
• Import Connection from pyrfc library: from pyrfc import Connection

Output:

@sebastiantaurer seems you are running Python 3.6.8

pyrfc 3.3.1 requires Python >=3.8
