とするとき、このエラーが出ます私はlocalhost：3000/tripを私のブラウザで開きます。 申し訳ありませんが、何かが間違っていました。

「この問題については通知されており、まもなくそれを見ていきます。」

これはなぜ起こっているのですか？

Answer 1

sqlite3 gemとそのパッケージをインストールする

Answer 2

答えはno such file to load -- sqlite3です。あなたはgem install sqlite3とsqlite3の宝石をインストールする必要があります。

私は質問しなければなりませんが、どうして古いバージョンのRailsを使用していますか？あなたが2.3に固執する必要があるならば、あなたは少なくともバージョン2.3.11に行くべきです。
