java - in thread "main" java.lang.UnsatisfiedLinkError: no jnilept in java.library.path

Question

I have created a project for OCR

TessBaseAPI instance =  new TessBaseAPI();
instance.Init("C:\\TIAA Info\\tessdata","eng");
PIX image = lept.pixRead("C:\\TIAA Info\\tessdata\\test.png");
instance.SetImage(image);
BytePointer bytePointer = instance.GetUTF8Text();
String output = bytePointer.getString();
System.out.println(output);

After executing , I am getting following error

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jnilept in java.library.path

我遇到了同样的错误，原来只是我默认为 32 位项目，示例是 64 位。改变了这一点，它工作得很好。
