问题描述

在使用 python3 使调用 aiohttp 库时候
遇到 ssl 连接错误 network is unreachable 错误

参考下面部分日志信息

2021-12-03 10:28:53,345 ERROR: Error syncing package: metapathways-v2-0@1178955 (mirror.py:363)

解决方法

修改

/usr/local/python3/lib/python3.8/site-packages/aiohttp/client.py

        trust_env: bool = True,

/usr/local/python3/lib/python3.8/site-packages/aiohttp/connector.py

     verify_ssl: bool = False,

下载超时

由于下载 pypi.org 软件时，当包特别大，可能会遇到超时
尝试修改一下下面超时时长

/usr/local/python3/lib/python3.8/site-packages/aiohttp/client.py

DEFAULT_TIMEOUT: Final[ClientTimeout] = ClientTimetout(total = 5 * 60)
