QUESTION
I'm invoking nameko shell inside my docker container of the example service, but I receive this error. I have setup two containers. My rabbitmq container and my service container. I'm invoking the nameko shell from inside the service container bash. The containers start up correctly and the service container connects successfully. But I can't use the shell.
ANSWER
Answered 2020-Sep-18 at 07:55I found out after a while that it was my own stupid mistake. I forgot to add the config file in my nameko shell command. You have to specify the message broker when executing nameko shell. In my case I needed to run nameko shell --config config.yml. That enabled me to connect and test my nameko service.

ANSWER
Answered 2020-Sep-10 at 17:23Based on the stack trace you provided here, it is evident you're working within a Windows environment. nameko does not support Windows-based environments. There is an open issue in the nameko GitHub repository requesting support for Windows (among others), but there hasn't been any movement on this since April 2019.
Specifically, Python's os.register_at_fork method, the one that's causing your error ("AttributeError: module 'os' has no attribute 'register_at_fork'"), is only available on Unix-based systems.
QUESTION
I wanted to install SQLAlchemy for Python 3 for working with databases.
I searched for the package using pip3 search SQLAlchemy, but I didn't find SQLAlchemy as part of the results.
Why don't SQLAlchemy show up in the output below, when the package is available on PyPI?
https://pypi.org/project/SQLAlchemy/
SQLAlchemy 1.3.15

Vulnerabilities
No vulnerabilities reported
Install nameko
You can use nameko like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
