为什么我在安装 python 的 psutil 包时会出错？

Question

我在 windows 64 位机器（版本 3.10）上安装了 pyhton。之后我喜欢安装 psutil：

python -m pip install psutil

但我收到以下错误消息：

这里有什么问题？？

Answer 1

安装缺少的包pip install wheel

安装这个工具https://visualstudio.microsoft.com/visual-cpp-build-tools/

安装时勾选此选项=>

重启你的机器。

运行cmd中的这个命令pip install --upgrade setuptools

现在您可以运行在cmd中执行此命令pip install psutil

终于上线了运行！ :-D ;-) 现在在我的机器上测试（win10, python 3.10.0, pip 21.3）！祝你好运！最好的问候：-D
