Question

我尝试在 Raspberry Pi 上的 Python3.7 上使用 gevent 运行我的 Flask 项目，第一行是 gevent.monkey.patch_all()。但它最终出现了这个错误：

 OverflowError: Python int too large to convert to C long

在我的 PC (Python3.8) 上，一切正常，我收到此警告：

init.py:1: MonkeyPatchWarning: Monkey-patching ssl after ssl has already been imported may lead to errors, including RecursionError on Python 3.6. It may also silently lead to incorrect behaviour on Python 3.7. Please monkey-patch earlier. See https://github.com/gevent/gevent/issues/1016. Modules that had direct imports (NOT patched): ['urllib3.util (/usr/local/lib/python3.8/dist-packages/urllib3/util/__init__.py)', 'urllib3.util.ssl_ (/usr/local/lib/python3.8/dist-packages/urllib3/util/ssl_.py)'].

我需要补丁猴子，因为当我删除它时，其他一切都运行良好，但是从外部线程发出的套接字正在堆叠和缓冲，并在很长时间后到达 JavaScript 处理程序。

我的模块版本：

Flask==1.1.2
Flask-SocketIO==5.0.1
python-engineio==4.0.0
python-socketio==5.04
gevent==20.12.1
gevent-websocket==0.10.1

有谁知道，我该如何解决这个问题？

谢谢。

问题是我在 RPi 上运行的是 32 位而不是 64 位的 Python3。
