你正在尝试编译一些简单的请求 DEV 包的东西，你只有 Python 解释器包，在 Raspberry PI 中你必须有 python-dev 和 python3-dev 为例，如果你使用的是树莓派尝试运行:

You are trying to compile something that is simple requesting the DEV packages, you have only the Python interpreters packages, in Raspberry PI you must have python-dev and python3-dev for example, if you are using Raspberry PI try to run:

sudo apt-get install -y python-dev python3-dev

然后你会通过这一步，如果有其他错误再发新帖.

Then you will pass this step, if there come another errors make new posts.
