尝试修复的步骤:

1)重新安装XCODE

2)重新安装XCODE命令行工具

3)读取堆栈溢出上的类似错误

替代问题:

1) zlib应该预先安装,我可能会遇到什么样的问题？

2)将python手动安装到pyenv中的另一种方法是什么？pynev也可以识别？

我有同样的问题。首先我尝试手动安装 python

./configure --prefix /usr/local/var/pyenv/versions/3.5.5/
make
make install

构建已完成，但我也遇到了有关 openssl 和 zlib 的错误。然后我再次尝试更改构建环境：

export CPPFLAGS="-I/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include -I$(brew --prefix openssl)/include"
export LDFLAGS="-L/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib -L$(brew --prefix openssl)/lib"

哪个成功了。

最后我在同一个 shell 中运行（带有两个导出的变量）：

pyenv install 3.5.5

这也成功了:-) HTH
