[PYTHON] [Solved] ImportError: No module named pyexpat and pyenv install is moss

~~ I'm sorry. It's still unsolved. If you have solved it in the past, I would appreciate it if you could give me some advice. ~~

It seems that it has moved somehow.

How to fix

Now it works! 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"

But I don't know why it didn't work and why it was fixed. .. ..

The following process

I got an error when trying to install 3.5.2 with pyenv

$ pyenv install 3.5.2

Even on github, I was told "Because it's broken ('-`) Silane"

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

Isn't pyenv installed via homebrew wrong?

I want to do something that wasn't there once.

Let's erase PYENV_ROOT

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

For the time being, I will delete the association that I put in via brew

$ brew uninstall pyenv python

Install pyenv again

$ brew install pyenv

3.5.2 Re-challenge installation

$ pyenv install 3.5.2

No, it's no good!
