nameko 无法适配新版的python3.14，eventlet 停止维护导致的 1 RLock(s) were not greened 报错
用于测试的代码
from nameko.rpc import rpc
class HelloService:
name = "hello_service"
@rpc
def hello(self, name):
return "Hello, {}!".format(name)直接把 nameko2.14.1 用到 python3.14 上会报错 ModuleNotFoundError: No module named 'pkg_resources'
修复之后还是会有警告
╰─➤ nameko run --config config.yaml run_services
1 RLock(s) were not greened, to fix this error make sure you run eventlet.monkey_patch() before importing any other modules.
starting services: greeting_service
Connected to amqp://ponponon:**@192.168.31.245:5672//这个 1 RLock(s) were not greened 不是因为 nameko 的问题，而是来自 eventlet 本身的问题：https://github.com/eventlet/eventlet
我通过降低 cpython 版本做测试，发现 cpython3.13 也有这个问题；直到降级到 cpython3.12 则没有这个问题了
而大于 3.12 的版本就会遇到下面的问题
