tesseract-ocr gem が正しくインストールされている (依存関係を含む)。ただし、Rails サーバーを起動すると、次のコンパイル エラーが発生します。この段階でコンパイル エラーが発生したことは一度もありません。

私が見る限り、あなたはmac osを使用しています...インストールの間違いを解決する最も簡単な方法は、クリーンインストールです:)tesseractとgem 'tesseract-ocr'

自作をインストールしている場合はかなり簡単です

$ brew install tesseract

しばらく時間がかかり、tesseract自体と必要なすべてのライブラリがインストールされます

そしてその後、もちろん

$ gem install 'tesseract-ocr'

（または$ bundle installGemfileに追加した場合）
