如何安装psutil以及提示缺少python.h头文件

下载psutil

下载地址https://pypi.python.org/packages/57/93/47a2e3befaf194ccc3d05ffbcba2cdcdd22a231100ef7e4cf63f085c900b/psutil-5.2.2.tar.gz#md5=bb98d48796cd76d9ccee871aad720f9c

解压

进入解压后的文件夹

安装

python setup.py install

我的会报错，解决方法是安装python-devel

过程如下

。。。。该部分内容太多省略，安装成功

重新进入python，导入psutil不再报错
