python3.7（pip3）でscikit-learnをインストールしようとしたらエラった話
mac初期化して、綺麗さっぱり！
もう一度環境設定し直そうと思って機械学習系のライブラリ入れてたらなんかエラーになったのでログとして残しておこうかなと思います。
エラー内容
どういう動作をしていたかは以下です。
- homebrewでpython3をインストール
- pipでscikit-learnをインストトール
$ brew update # brewをインストールしていたので最新にした $ brew doctor # 問題ないか確認 Your system is ready to brew. $ $ pip3 install scikit-learn # scikit-learnをインストール ・・・エラー出る

対処方法
調べてみたところ一昨日くらいに修正されマージされていたみたい。 なので最新のをインストールすれば良い。 brewに反映されるまで1ヶ月くらいかかるということなので、(8月には治っているかな？)それまでpythonのバージョンを下げれば インストールできるよとのこと！（本当かどうかは試していないのでわかりませんが・・）
Note that you would need Cython >=0.27.3 to compile it..
ということなのでCythonをインストールしてからdevの最新を入れたら通りました！
