Nuxt 2.5.1にアップデートしてから、nuxt run devの実行時に表題のエラーが出たのでメモ。

環境

Nuxt v2.5.1
Node.js v11.12.0

エラー内容

コンパイル中にfriendly-errorsが山ほど出た。

最後の行に足りないパッケージをインストールするようにとあった。

$ npm install --save core-js/modules/es6.array.find core-js/modules/es6.ar...

実行したが解消しなかった。また、$ yarn add core-js`も同様にダメだった。

GitHubを確認

エラーを調べるとissues #3842に報告済みであり、クローズしていた。依存関係にバグがありcore-jsの依存関係が解消されなかったらしい。

もう少しググる

解決策は（多分）無かったのでもう少しググり、中華サイトに行き当たった。 segmentfaultという中華版Stack OverFlowみたいなサイト。

解决liunx系统，项目nuxt2.0运行npm run dev / start报错问题

$ npm install --save core-js@latest2.6.2

最新版のcore-jsが必要そうなので、yarnで実行してみた。

$ yarn add core-js@latest2.6.2
yarn add v1.15.2
