gevent worker是否可以在python 3 app引擎标准环境中使用?

尝试使用它们会给我以下错误:

Traceback (most recent call last):
  File "/env/lib/python3.7/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker
    worker.init_process()
  File "/env/lib/python3.7/site-packages/gunicorn/workers/ggevent.py", line 196, in init_process
    self.patch()
  File "/env/lib/python3.7/site-packages/gunicorn/workers/ggevent.py", line 75, in patch
    fileno=s.sock.fileno()))
  File "/env/lib/python3.7/site-packages/gevent/_socket3.py", line 114, in __init__
    self._sock = self._gevent_sock_class(family, type, proto, fileno)
OSError: [Errno 92] Protocol not available: 'protocol'

python 3环境中不支持套接字吗?这是它不起作用的原因吗?

我的应用程序在其他Web服务器上花费了很多时间,因此必须使用异步工作器才能获得良好的性能。同时,我将尝试改用eventlet个工作程序。

编辑:包括更多有关用法的上下文

app.yaml

runtime: python37
instance_class: F2

entrypoint: gunicorn -c gunicorn.conf.py -b :$PORT my_project.server:app

gunicorn.conf.py

# Recommended number of workers based on instance size:
# https://cloud.google.com/appengine/docs/standard/python3/runtime#entrypoint_best_practices
workers = 2
# Use an asynchronous worker as most of the work is waiting for websites to load
worker_class = 'gevent'

由于它是在启动gunicorn期间,所以我认为应用程序定义上下文不会有用。但是为了完整起见,我正在启动一个基本的flask应用程序。像这样:

my_project / server.py

from flask import Flask

from my_project.handlers import run

app = Flask(__name__)
app.register_blueprint(run, url_prefix='/run')

我有同样的错误。我想如果要使用 gevent ,我们仅限于 GAE Flexible GKE上的Cloud Run

GAE Standard 在沙盒(gVisor)中运行,并且某些操作受到限制(我注意到此尝试的 Cloud Run 存在相同的问题> gevent

您看到的错误是这个:

Container Sandbox Limitation: Unsupported syscall 
getsockopt(0x5,0x1,0x26,0x7e11bd8ddf20,0x7e11bd8ddf24,0x4)
