pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

问题场景：
在用pip install y:\emailgetcontent\dailycapacitychart\pkgs\pypiwin32-223-py3-none-any.whl安装时出现：pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host=‘files.pythonhosted.org‘, port=443): Read timed out.

大致的意思就是请求安装源（我的源已下载到本地）超时。

解决方案：设置延长默认超时时间 pip install --default-timeout=1000 y:\emailgetcontent\dailycapacitychart\pkgs\pypiwin32-223-py3-none-any.whl

总结：修改默认超时时间进行安装，缺点就是安装起来会很慢（虽然我已经把安装包下载到本地了）

pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.
