使用 pip 安装包会返回错误

Question

不久前，我从https://pip.pypa.io/en/stable/installing/下载了 pip ，然后才意识到我的 python 版本已经附带了 pip。我成功地使用它来下载 pygame，但现在我正在尝试下载 numpy，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，如果有的话。无论如何，这只是我的理论。

这就是当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，因为它会转到错误页面。请帮助我，如果没有我尝试安装的软件包，我将无法执行任何操作。解决方案将不胜感激。

编辑 这篇文章不是与已建议的其他问题重复的，这是重复的，因为我不相信该问题的情况或答案与我的问题有关。

尝试这个：

C:\Users\riley> pip install --trusted-host pypi.org numpy
