Question

最近我开始在一家大公司工作。我已经安装了python，现在正在尝试安装软件包（使用pip，已安装），但是出现以下错误（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

因为我知道我收到了错误，因为我在公司网络中尝试了以下内容（因为StackOverflow上的其他人也这样做了）：

> 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

有谁能告诉我出了什么问题以及如何解决这个问题？我的工作笔记本电脑运行Windows 10。

如果有人可以提供帮助，我将非常感激。

问题已经解决了。该公司使用代理，如果暂时关闭，我可以安装包没有问题。

我希望这能帮助处于同样情况的其他人
