Question

我是原生Linux用户和开发人员，但由于我现在在工作中使用Windows 10，因此我在个人计算机上执行通常最基本的任务时遇到了一些麻烦。我已经从现有代码创建了一个python项目，但需要为它安装所需的模块。我尝试按照MSDN说明访问工具 - > Python工具 - ＆gt; Python环境。

这个过程似乎有点自我解释，但是当我尝试升级pip时，我收到了这个错误

Cannot fetch index base URL https://pypi.python.org/simple/ 我在尝试点击安装NumPy时收到同样的错误

我目前真正需要的模块虽然来自github存储库而不是PyPi。通常我会像这样安装它

pip install https://github/u/r/l/file.zip

但这会返回不同的错误。完整输出在我的点差错误日志中就像这样

有谁知道问题可能是什么？

Windows的10 发生在Visual Studio 2015和2017中 python 3.4和3.6 pip 1.5.6和pip 9.0.1

Answer 1

由于错误提及，最大重试错误，这意味着可能存在连接问题。确保您的网络管理员允许您下载软件包

Answer 2

初始异常显示为getaddrinfo failed，表示DNS解析失败。我会运行nslookup github.com并查看它是否已解决。
