关于os x编译时提示缺少“Python.h”解决方案

文章首发地址：https://blog.aosan825.top/index.php/archives/5/

emmmm, 今天在编译webots时提示缺少,bing搜到的解决方案有两个：

1. 直接brew install python
2. 安装python-devel
   第一个毫无疑问是没有卵用的，每次开始用新系统之前就是用这个命令来安装python，所以选择解决方案2
   关于python-devel安装方法我搜到了两种，一个是直接brew install python-devel(反正我没搜到这个包)，另一个是用pyenv来安装。

brew install pyenv
pyenv install 3.7.3

然后报错。。。

python-build: use openssl 1.0 from homebrew
python-build: use readline from homebrew

艹（中国语），继续搜索解决方案

xcode-select --install
brew update
brew install pyenv
pyenv install 3.6.3
pyenv global 3.6.3

CSDN上基本都是这个，结果第一条命令就出问题了：

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

换搜索引擎，搜到一个日本前辈的博客，给了个解决方案：

$ sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

执行，问题解决，草(日本语)

更新：发现一个更简单的解决方案，直接安装Python官网的PKG不会出现这个问题。。。。
