Python 使用pip安装程序包时返回错误

不久前，我从 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

我尝试重新安装pip和python，但没有任何改变。我想这与我无意中从上面的链接下载了pip并拥有两个版本的pip有关。当我卸载pip时，它并不是被卸载的那个，如果这些都有意义的话。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

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 这篇文章并不是被建议的另一个问题的复制品，这是一个复制品，因为我不相信这个问题的情况或答案与我有关。

试试这个：

C:\Users\riley>pip安装——可信主机pypi.org numpy
