【第54日目】42歳の金のないキモいおっさんがブロックチェーンエンジニアを目指す日記「まだ開発環境構築でつまづいてます」

【双極ライフハッカー】ひろあき

こんばんは。ひろあきです。2日ぶりのnote更新です。まだ元気です。

前回のnoteで、イーサリアムでの開発環境構築でつまづいてる件を書きましたが、参考にさせていただいているnoteの作者さんにコメント欄で助けを求めたところ、すぐに的確なアドバイスをいただけ、その件については解決しました。DaiDaiさん、ありがとうございました。しかし、一難去ってまた一難。今度はこんなエラーが…。

どうも自分はこのnpm（node.jsのパッケージ管理ツールらしい）と相性が悪いみたいです。ただ、今回はちょっと心当たりがあって、これが怪しいと思うですよね。それが以下の画面になります。

npmを実行する前段階として、build-essentialというのをインストールしなければならないのですが、地味にそこでエラーが出ていてちゃんとインストールされてないっぽいんですよね。こいつが怪しい…。明日以降ここを攻めてみます。それでは今日はこの辺で。おやすみなさい。
