用pip安装软件包返回错误[重复]

Question

不久前，我从https://pip.pypa.io/en/stable/installing/在我意识到我的python版本allready附带了pip之前。我成功地使用它下载了pygame，但现在我正在尝试下载numpy，无论我尝试了什么，它都会返回下面的错误。

我已经尝试重新安装pip和python，但没有任何改变。我认为这与我不小心从上面的链接下载pip并拥有两个版本的pip有关。当我卸载pip时，它不是被卸载的那个，如果有任何意义的话.不管怎样，这只是我的理论。

这就是我尝试安装任何东西时发生的情况

C:\Users\riley>pip install numpy

这也可能与链接有关，因为它指向出错的页面。请帮助我，如果没有我试图安装的软件包，我将无法执行任何操作。我们将不胜感激。

编辑这篇文章不是一个重复的其他问题，已建议这是一个重复的，因为我不相信的情况或该问题的答案是与我有关。
