在Mac上安裝 tesseract 成功後，使用tess4j 出現這個錯誤

Error opening data file ./eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!

解決辦法進入到 /usr/local/Cellar/tesseract/4.1.1/share/tessdata 把eng.traineddata 加入到工程目錄中
