events.js：141 throw er; //未処理の「エラー」イベント

私はMac OSでノード4.2.2を実行しようとしていますが、このエラーメッセージが表示されるたびに理由がわかりません：

events.js:141
      throw er; // Unhandled 'error' event

何が悪いの？ 「gulp build」を実行すると、次の出力があります。

同じポートで他のターミナルが他のアプリケーションを実行しているかどうかを確認します。これは、複数のアプリケーションが同じポートにアクセスしようとしたときに発生します。常にFIFOです。

幸運を！！！

同じポートで実行されている他のアプリケーションのファーストルックは、別のノードアプリケーションである可能性があります。

同じポートで実行されている現在のプロセスを見つけるには、次を使用します。

マック：

Netstatを試すことができます

netstat -anp tcp | grep 3000

OSX "El Capitan"の場合、またはnetstatが-pをサポートしていない場合は、lsofを使用します

lsof -i tcp:3000

その後、プロセスを強制終了します

kill pid

すべてのノードプロセスの使用を強制終了することができます。

killall -9 node

問題を修正しました。 assetsのパーミッションに問題がありました-gulpがすべてのアセットを取得できない場合。その後、常にエラーが表示されます。アセットを手動で削除しました。 「Sudo」コマンドに注意する必要があると思います...

したがって、エラー、未処理の「エラー」イベントをスローします。つまり、エラーイベントを処理し、このイベントに関数を追加してエラーを出力する必要があることを意味し、理由がわかり、プログラムは正常に動作します.

これはエラーには関係しませんが、端末から同じアドレスを持つ複数のサーバーで同時にノードを実行している場合、そのエラーコードも実行できます。

ENOENTは、spawnが探しているバイナリを見つけられなかったことを意味します。 spawnにしようとしているものがパスにあることを確認してください。

この場合、おそらくgifsicleはインストールされていません。

Mac Book Proでも同じエラーが発生しました。解決策はありません。コンピューターを再起動することで、ようやく問題を解決しました。夜間にコンピューターの電源を切ってスリープモードにしないことが多いので、コンピューターが長時間実行されている場合は、再起動してみて、動作するかどうかを確認してください。
