Python headers not found错误解决办法
安装Python扩展时，Configure error: Python headers not found错误解决办法
在安装spot时，遇到#include "Python.h"找不到错误：
checking Python.h usability... no
checking Python.h presence... no
checking for Python.h... no
configure: error: Python's development headers are not installed.
原因：
无法找到 python 库，#include "Python.h" 出错 ，缺少python-dev或python3-dev
解决:
使用 apt (Ubuntu, Debian…) 安装
sudo apt-get install python-dev # for python2.x installs
sudo apt-get install python3-dev # for python3.x installs
使用 yum (CentOS, RHEL…) 安装
sudo yum install python-devel # for python2.x installs
sudo yum install python34-devel # for python3.4 installs
使用 dnf (Fedora…) 安装
sudo dnf install python2-devel # for python2.x installs
sudo dnf install python3-devel # for python3.x installs
使用 zypper (openSUSE…) 安装
sudo zypper in python-devel # for python2.x installs
sudo zypper in python3-devel # for python3.x installs
使用 apk (Alpine…) 安装
sudo apk add python2-dev # for python2.x installs
sudo apk add python3-dev # for python3.x installs
