我pyenv在安装其他python版本时总是收到这个zlib构建错误。
我已经尝试了一些网上的办法但是都不太实用，最后找到了一个最全的方法，具体如下：

1.用brew安装zlib openssl 等缺少的库

brew install zlib
brew install openssl
brew install readline

2.安装前添加编译环境变量

export LDFLAGS="-L$(brew --prefix zlib)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix openssl)/lib"
export CPPFLAGS="-I$(brew --prefix zlib)/include -I$(brew --prefix readline)/include -I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include"

3.最后进行安装

pyenv install 2.7.5

执行过程：

[sleeli@MacBook-Pro:] ~ $ export LDFLAGS="-L$(brew --prefix zlib)/lib -L$(brew --prefix readline)/lib -L$(brew --prefix openssl)/lib"
[sleeli@MacBook-Pro:] ~ $ export CPPFLAGS="-I$(brew --prefix zlib)/include -I$(brew --prefix readline)/include -I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include"
