rasberry pi 3 b+ でflask-askがインストールできない

Question

問題点

flask-askをインストールしようとして、ラスベリーパイのコマンドで
pip3 install flask-ask　
を行ったら、
Segmentation fault
が出てしまいました。
pythonのflask_askをimportで使うプログラムが動きません。
どうしたら、いいですか？

バージョン

pip 9.0.1

pcbginerさん、

RaspberryPi 3B+, Raspbian Stretch, Python3.5.3, pip3 9.0.1、の環境で、rootで実行してますが、Segmentation faultは出てきませんでした。

なにか、ファイルが壊れているのかもしれないので、OSのインストールから、再度やってみるのはどうでしょうか？
