Python安装软件包出错

今天用pip安装软件包,死活安装不上,出现如下错误:

Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x10f5a7748>: Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known')': /packages/5c/e0/be401c003291b56efc55aeba6a80ab790d3d4cece2778288d65323009420/pip-19.1.1-py2.py3-none-any.whl

还以为是特定软件包的问题,很快发现升级pip也有问题。

网上找了一圈,把代理、vpn等都关了,问题依旧。仔细看错误的最后一行,看到有files.pythonhosted.org这个域名,心想难道这个域名挂了?

ping这个域名,竟然提示解析错误。于是登陆到境外的服务器上ping,解析正常。想到应该是dns解析问题,接着把dns换成了1.1.1.18.8.8.8,再次安装,问题顺利解决。
