Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
  /Users/ogawakiyoshi/.pyenv/shims/icu-config
  /Users/ogawakiyoshi/.pyenv/shims/libpng16-config
  /Users/ogawakiyoshi/.pyenv/shims/python3.6m-config
  /Users/ogawakiyoshi/.pyenv/shims/python-config
  /Users/ogawakiyoshi/.pyenv/shims/python3-config
  /Users/ogawakiyoshi/.pyenv/shims/python3.6-config

Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

  /usr/local/lib/libLTO.dylib

Warning: Unbrewed header files were found in /usr/local/include.

Warning: Unbrewed static libraries were found in /usr/local/lib.

$ brew prune

$ cat $HOME/.local/lib/python3.6/site-packages/homebrew.pth
import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")

homebrew.pth編集

記事の指摘どおり、3.6で2.7を参照している。
記事との唯一の違いは、コメントや削除するのではなく、2.7を3.6に書き換えた。もし、3.6に有効なデータが他にも蓄積されたときに役立つかもと思い。

これが新たなエラーを産んだら報告します。

$ vi $HOME/.local/lib/python3.6/site-packages/homebrew.pth
$ cat $HOME/.local/lib/python3.6/site-packages/home-brew.pth
import site; site.addsitedir("/usr/local/lib/python3.6/site-packages")
