WARNING: The Python bz2 extension was not compiled. Missing the bzip2 lib? WARNING: The Python readline extension was not compiled. Missing the GNU readline lib? WARNING: The Python sqlite3 extension was not compiled. Missing the SQLite3 lib?
拡張機能が足りないけどいいすか？みたいな内容らしい。
それぞれapt-getすればOK。
$ sudo apt-get update
$ sudo apt-get install -y libbz2-dev libreadline-dev libsqlite3-dev
