npm installをすると、Cannot convert undefined or null to objectというエラーが出ます。
zsh
1$ npm install 2npm ERR! Linux 4.15.0-34-generic 3npm ERR! argv "/usr/bin/node" "/usr/bin/npm" "install" 4npm ERR! node v8.10.0 5npm ERR! npm v3.5.2 6 7npm ERR!

Cannot convert undefined or null to objectのundefinedやnullというのは何を指すのでしょうか。
npmの問題なのか、package.jsonの問題なのか、、分かりません。

この質問を載せた後に、core-util-is-2@1.0.2だけをpackage.jsonから消してインストールしたら、成功しました！
しかし、core-util-is-2@1.0.2がなぜインストールできないのかが分かりません。。。
パッケージが見つからないということでしょうか？

package.jsonの書式が間違っています。
以下のように修正してください。
