【问题描述】：

前段时间我从https://pip.pypa.io/en/stable/installing/下载了pip 在我意识到我的 python 版本已经带有 pip 之前。我成功地用它来下载 pygame 但现在我正在尝试下载 numpy 并且无论我尝试什么它都会返回以下错误。

我尝试重新安装 pip 和 python，但没有任何改变。我认为这与我从上面的链接意外下载 pip 并拥有两个版本的 pip 有关。当我卸载 pip 时，它不是被卸载的，如果有任何意义的话。无论如何，这只是我的理论。

当我尝试安装任何东西时会发生这种情况

C:\Users\riley>pip install numpy

这也可能与链接有关，因为它会转到错误页面。请帮助我没有我要安装的软件包做任何事情。解决方案将不胜感激。

编辑 这篇文章不是其他问题的重复，因为我不相信该问题的情况或答案与我的有关。
