从 greenlet 内部调用 trio

Question

我试过这个：

import trio
from gevent import monkey, spawn

monkey.patch_all()

async def async_double(x):
    return 2 * x

def run():
    return trio.run(async_double, 3)

g = spawn(run)
g.join()

但是我收到错误：

Traceback (most recent call last):
  File "src/gevent/greenlet.py", line 908, in gevent._gevent_cgreenlet.Greenlet.run
  File "/Users/xxx/t.py", line 10, in run

    force_wakeup_event = select.kevent(
AttributeError: module 'select' has no attribute 'kevent'

我也尝试先导入和修补 gevent，但在运行之前就失败了：

from gevent import monkey, spawn
monkey.patch_all()
import trio

追溯：

  File "/Users/xxx/t.py", line 3, in <module>
    import trio
  File "/Users/xxx/Library/Python/3.9/lib/python/site-packages/trio/__init__.py", line 18, in <module>
    from ._core import (
  File "/Users/xxx/Library/Python/3.9/lib/python/site-packages/trio/_core/__init__.py", line 27, in <module>
    from ._run import (
  File "/Users/xxx/Library/Python/3.9/lib/python/site-packages/trio/_core/_run.py", line 2458, in <module>
    raise NotImplementedError("unsupported platform")
NotImplementedError: unsupported platform

我想我有时设法让第一种方法（首先导入三重奏）工作（但代码有点不同并且更复杂），但我想知道这是否只是幸运并且稍后会出现问题。

这是在 MacOS 上，但需要跨平台。
