質問

Google Colaboratoryでmecabをインストールできなくなりました。

こちらのサイトを参考にし、

command
1!apt install aptitude
2!aptitude install mecab libmecab-dev mecab-ipadic-utf8 git make curl xz-utils file -y
3!pip install mecab-python3

というコマンドを実行することで以前まではmecabをインストールできていたのですが、2018年11月20日現在では下のようなエラーを吐き出しました。

どなたかご教授お願いいたします。。。
