python pip安装返回SSL错误

Question

最近我开始在一家大公司工作。我已经安装了python，现在正试图安装软件包（使用已安装的pip），但出现以下错误（numpy是一个示例，但每个软件包都会出现此错误）：

> pip install numpy
Collecting numpy
  Could not find a version that satisfies the requirement numpy (from versions: )
No matching distribution found for numpy

因为我认为我之所以会出错，是因为我在一个公司网络中，所以我尝试了以下操作（因为StackOverflow上的其他人也这么做了）：

> pip -vvv install numpy
Collecting numpy

  Starting new HTTPS connection (1): pypi.python.org
  Could not fetch URL https://pypi.python.org/simple/numpy/: connection error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) - skipping

有人能告诉我出了什么问题，我该怎么解决吗？我的工作笔记本电脑运行windows 10。

如果有人能帮忙，我将不胜感激。

问题已经解决。该公司使用代理，如果暂时关闭，我可以毫无问题地安装软件包。

我希望这能帮助其他处于相同情况的人
