【已解决】Error opening data file ./chi_sim.traineddata Please make sure the TESSDATA_PREFIX environment

报错内容：

Error opening data file ./chi_sim.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your “tessdata” directory.
Failed loading language ‘chi_sim’
Tesseract couldn’t load any languages!
Warning: Invalid resolution 0 dpi. Using 70 instead.

解决方法：

1. 设置环境变量(先下载服务 brew install tesseract)，我是设置了还不行

   export TESSDATA_PREFIX=/usr/local/Cellar/tesseract/4.1.1/share/tessdata
   

2. 手动设置字库路径
