piplocustconfluent-kafka-pythonpython-3.11

Unable to upgrade Python 3.11 due to error in Locust-plugin installation (Confluent-Kafka)


After upgrading Python to 3.11, Locust-plugin fails to install as one of its dependency throws error

  1. First it asked me to install VC++ > 14.0
  2. After installing VC++ build tools 15, still it throws a different error

Note: We do not see this issue until Python 3.10.8

Kindly let me know if there is any fix?

locust-plugins==2.7.1
  - confluent-kafka [required: Any]
DEPRECATION: confluent-kafka is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 2
3.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Solution

  • Right now there is currently no pre-built version of confluent-kafka for 3.11. Hopefully it is on the way though: https://github.com/confluentinc/confluent-kafka-python/issues/1452

    Also, I think the reason cannot build from source is that you need librdkafka installed. I dont know what the windows equivalent is, but apparently someone got it working on Linux this way:

    apt-get install -y --no-install-recommends gcc git libssl-dev g++ make && cd /tmp && git clone https://github.com/edenhill/librdkafka.git && cd librdkafka && ./configure --prefix=/usr && make && make install
