    pip install *** :Cannot connect to proxy

    在使用pip install 安装任何新的包都会出现下面错误:

    PS C:\WINDOWS\system32> pip install django

    出现这样的问题的原因是代理出现了问题,安装了蓝灯出现的。只要关闭蓝灯, pip install 就会提示上面的bug。

    解决办法

    按Win+R快捷键,输入regedit,打开注册表编辑器找到HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Internet Settings分支,把它下面以 Proxy 打头的键值对(如ProxyEnable,ProxyOverride,ProxyServer等)全部删除。

    这样再次 pip install 就可以了。

    python requests proxies 错误

    ProxyError: HTTPSConnectionPool(host='www.zhihu.com', port=443): Max retries exceeded with url: / (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x03CEFB50>: Failed to establish a new connection: [Errno 10060] ',)))

    SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:590)

    ConnectionError: ('Connection aborted.', BadStatusLine("''",))

    如果是初次使用代理,以上三种错误出现的原因基本是1.端口错误2.代理类型不正确。

    明确的一点是访问https站点,要用https类型的代理。http同理。

    如图

    西刺代理分的比较明确

    第一次用的时候就是因为这个浪费我半天时间。。

    总结

    以上为个人经验,希望能给大家一个参考,也希望大家多多支持3672js教程。
