Mac使用pyenv安装Python出现The Python zlib extension was not compiled. Missing the zlib错误

参考这里，详细如下：

On Mac OS X 10.9, 10.10 and 10.11 you may need to set the CFLAGS environment variable when installing a new version in order for configure to find the zlib headers (XCode command line tools must be installed first):

CFLAGS="-I$(xcrun --show-sdk-path)/usr/include" pyenv install -v 2.7.7

Alternatively, try reinstalling XCode command line tools for your OS (especially if you just upgraded your OS)

xcode-select --install
