[解決済み] cannot load such file -- sqlite3/sqlite3_native (LoadError) on ruby on rails

質問

Ruby 2.0.0 上で Rails 4.0.0 を使って基本的なインストールとサーバの起動を設定しようとすると、以下のエラーメッセージに直面します。

/usr/local/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:6:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError)

このエラーメッセージを回避し、先に進むにはどうしたらよいでしょうか？

どのように解決するのですか？

sqlite3 の gemspec ファイルを探します。一例を挙げると /usr/local/share/gem/specifications/sqlite3-1.3.7.gemspec

Windowsの場合。 C:\Ruby21\lib\ruby\gems\2.1.0\specifications .

Rubygemのパスとsqlite3のバージョンによって調整してください。 上のファイルを編集して、次の行を探します。

s.require_paths=["lib"]

に変更する。

s.require_paths= ["lib/sqlite3_native"]
