I had this problem too.
我也有这个问题。
Did you run the following after installing tesseract:

You must set LD_LIBRARY_PATH environment variable to the path where libtesseract.so is.
您必须将 LD_LIBRARY_PATH 环境变量设置为 libtesseract.so 所在的路径。
export LD_LIBRARY_PATH=/usr/local/lib

It is necessary to define the variable jna.platform.library.path. For instance:
有必要定义变量jna.platform.library.path。例如：
-Djna.platform.library.path=/usr/local/lib/
-Djna.platform.library.path=/usr/local/lib/

Maybe it is a 32 bit library .soinstalled.
可能是.so安装了 32 位库。
