“TypeError：无法使用 google-cloud-compute 将原型文件构建到描述符池中”

Question

我正在 Ubuntu 22 上使用 Python 3.13.0 运行 Python 应用程序。

自从从 3.12 升级 Python 以来，运行应用程序时出现此错误：

TypeError: Couldn't build proto file into descriptor pool: duplicate symbol 'google.cloud.compute.v1.AccessConfig.__firstlineno__'

该应用程序是开源的，位于：https://github.com/VerinFast/verinfast

requirements.txt中的相关项目：

google-cloud-compute>=1.14.0

protobuf 不在requirements.txt 中，但必须由另一个包安装。

该错误是由导入 google-cloud-compute 触发的：

from google.cloud import compute_v1

所以我创建了一个名为 test.py 的单行文件：

from google.cloud import compute_v1

如果我运行它：

python test.py

我得到同样长的错误：

/usr/lib/python3/dist-packages/requests/__init__.py:87: RequestsDependencyWarning: urllib3 (2.2.3) or chardet (5.2.0) doesn't match a supported version!

来自 pip show protobuf：

并且 pip 显示 google-cloud-compute：

看起来 google-cloud-compute 或 protobuf 对于 Python 3.13 来说已经损坏了，这是不幸的，因为它是 10 月 7 日发布的。

寻找解决方法。

我尝试包装导入：

try:
    from google.api_core.exceptions import NotFound
    from google.cloud import compute_v1
    from google.cloud.monitoring_v3 import Aggregation, MetricServiceClient, TimeInterval, ListTimeSeriesRequest  # noqa: E501
except:
    print("Google Cloud libraries not imported. Skipping GCP instances.")
    compute_v1 = None
    MetricServiceClient = None
    Aggregation = None
    TimeInterval = None
    ListTimeSeriesRequest = None

这消除了错误，但我无法导入 Google Cloud 数据。

这是一个已知问题，许多其他人也报告过。

除了将 Python 降级到 3.12 并等待 protobuf 开发人员解决问题之外，似乎没有其他解决方法：https://github.com/protocolbuffers/protobuf/issues/18706
