Gauge Pythonでgauge run specsをするとTypeError: Descriptors cannot not be created directlyエラーが出る

はじめに

初めてGauge Pythonを実行する機会があり、起動がうまくいかなかったのでまとめます

問題

PythonでGaugeを実行したところ以下のエラーが出ました

$ gauge run specs

Traceback (most recent call last):

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Your Environment Information -----------
        linux, 1.4.3, f98dd40
        html-report (4.2.0), java (0.9.1), play-cdc (0.1.4), python (0.3.17), screenshot (0.1.0)

実行した環境のgauge pythonは0.3.17です

解決方法

以下を実行したところうまく動くようになりました

$ pip install --upgrade protobuf
$ export PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python

google.protobuf.descriptor.EnumValueDescriptorの直接作成が試みられており、これは新しいprotobufのバージョンでは許可されていないことが原因みたいです

今回はvenv上でいんすとーるしました

おわりに

個人的にはGauge Javaよりもつまづくことなく実行できたのでよかったです
