ubuntu16.04、pip3、python3.6在pyhon虚拟环境下安装mahotas软件包遇到的问题

在安装mahotas软件包时使用命令：

pip3 install mahotas

但是终端中报了一大段错，看的我头皮发麻：

Building wheel for mahotas (setup.py) ... error

挖掘上边报错的关键词、关键句 有以下几个：

ERROR: Command errored out with exit status 1: 
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
mahotas/numpypp/numpy.hpp:10:20: fatal error: Python.h: 没有那个文件或目录
ERROR: Failed building wheel for mahotas

我上网把上边的错误搜了一遍，主要有以下可能：
（1）如果是在windows下的python环境安装mahotas，可能是要下载whl文件：
http://www.lfd.uci.edu/~gohlke/pythonlibs/
ctrl+f找到mahotas，下载对应版本，比如cp36是python3.6，win32是32位系统，amd64是64位系统
（2）可是我的是Ubuntu系统耶，尝试：

sudo apt-get install python3-dev
sudo apt-get install libevent-dev

但是再次尝试安装还是不行。。。。
突然我想起了之前自己python3.5升级到python3.6时，仍然保持默认python3版本为python3.5.。。。。
应该是sudo apt-get install python3-dev安装了python3.5的头文件和静态库？？？于是执行：

sudo apt-get install python3.6-dev

再次执行安装命令后安装成功！！！！
