直った方法

これで動きました！
https://github.com/yyuu/pyenv/issues/448#issuecomment-220652296

export CFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib -L$(brew --prefix sqlite3)/lib"
export CPPFLAGS="-I$(brew --prefix sqlite3)/include"

しかしなぜダメで、どうして直ったのかは分かってないです。。。

以下経緯

pyenv で 3.5.2 をインストールしようとしたらエラーが出た

$ pyenv install 3.5.2

github でも「それ壊れてるから( ´ー｀)ｼﾗﾈｰﾖ」って言われてた

ImportError: No module named pyexpat · Issue #544 · yyuu/pyenv

homebrew 経由でインストールしたpyenvがおかしくなってしまったのではないか？

一旦なかった事にしたい。

PYENV_ROOTは消そう

$ echo $PYENV_ROOT
/usr/local/var/pyenv
$ rm -r /usr/local/var/pyenv

とりあえずbrew経由で入れた関連は消してみる

$ brew uninstall pyenv python

もう1回pyenvをインストールする

$ brew install pyenv

3.5.2 インストールを再チャレンジ

$ pyenv install 3.5.2

いや、ダメだし！

CFLAGS とやらを設定して再チャレンジ
