Python 一个 pip 报错 ProxyError 的处理

Windows 环境下，在 IE 中设置的代理 (连接-局域网设置) 是全局的，在 cmd 的命令也会使用那个代理。

遇到的问题

D:\pentest_tmp>python2 -m pip install prettytable
Collecting prettytable
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000000046A9E48>: Failed to establish a new connection: [Errno 10061] ',))': /simple/prettytable/
  Retrying (Retry(total=3, connect=None, read=None, redirect=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000000046A9748>: Failed to establish a new connection: [Errno 10061] ',))': /simple/prettytable/
