Question

我正在尝试捕获图像的文本，但是我得到了空指针异常，这是我正在使用的代码

我检查了几个链接，我认为问题是Mac系统还是32/64位，当前我正在使用64位macbook。有什么工作可以解决这种情况

  File src = 



 driver.findElement(By.id("CaptchaImage")).getScreenshotAs(OutputType.FILE);



String path = System.getProperty("user.dir")+"/screenshots/captcha.png";

    FileHandler.copy(src, new File(path));

    String path1 = System.getProperty("user.dir")+"/screenshots/captcha.png";

    ITesseract image = new Tesseract();

    String imageText = image.doOCR(new File(path1));

    System.out.println(imageText);

    imageText = imageText.replaceAll("[^a-zA-Z]", "");

    System.out.println(imageText);
    driver.findElement(By.xpath("//input[@name='CaptchaInputText']")).sendKeys(imageText);

这是我得到的错误：

8:57:42.210 [main] ERROR net.sourceforge.tess4j.Tesseract - null
java.lang.NullPointerException: null

执行doOCR函数时，发生错误net.sourceforge.tess4j.Tesseract-null
