Cannot find module

OS: Ubuntu 16.04.5 LTS, node v11.10.1

Installing Solid server with

sudo npm install -g solid-server

results following errors:

まず、指定された Ubuntu と Node のバージョンで報告された sudo npm install -g solid-server の失敗を再現し、次に spawn-sync@1.0.15 の postinstall ステップと、欠落している postinstall エントリポイントを調査します。グローバルインストールが Cannot find module エラーや postinstall ライフサイクルエラーなしに完了すれば完了です。
