PaizaCloudのサーバーで"npm init"コマンドがエラーになる

現在、paiza開発日誌の
Node.js入門：初心者でも10分でWebサービスを作れる！Node.jsとPaizaCloudの使い方

という記事を参考にゲーム制作をしようとおもっております。

この記事の「プロジェクトの作成」から先がうまくいきません。

ターミナルを起動したあと、

npm init -y myapp

と入力しましたが

npm ERR! code E404
npm ERR! 404 Not Found: create-myapp@latest

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/ubuntu/.npm/_logs/2018-07-26T11_08_59_642Z-debug.log
Install for create-myapp@latest failed with code 1

とエラーが出てしまいました。

エラーを発生させずに、コマンドを実行させるためには何が必要なんでしょうか。

また、ログファイルの中身は以下の通りでした。
