【问题描述】：

我最近重新安装了 python，因为导入和虚拟环境发生了奇怪的事情。

现在，当我尝试安装库时——例如 kivy——会发生这种情况：

此时，它只是卡住了。无论我是在虚拟环境中还是在虚拟环境之外进行操作都没有关系。我试过 pip 安装另外两个库：请求，它有效；和 matplotlib，它没有。

【解决方案1】：

我不知道为什么卡住了，但是我看到的是你使用的是python 3.10，它是如此新鲜，以至于我不得不去检查它是否已经发布（它是！5天前！）。

kivy 没有 3.10 的轮子，因此它试图从源代码构建一个，并且由于缺少 kivy-deps.gstreamer-dev 依赖项而崩溃，该依赖项仅是二进制文件，不适用于 python 3.10 .

我推断，您不太可能使用 python 3.10 安装 kivy。试试 3.9？

3.9 有效。谢谢你，互联网人。
