如何使用 pytesseract 修复这些错误？

Question

我正在尝试创建一个非常简单的程序，可以扫描屏幕的特定部分并打印找到的任何文本。由于某种原因，我遇到了一系列错误，我在网上找不到任何相关信息。

这是我写的代码。

from PIL import ImageGrab
import pytesseract

pytesseract.pytesseract.tesseract_cmd = r'C:\Users\chad\AppData\Local\Programs\Microsoft VS Code\bin\pytesseract.exe'

image = ImageGrab.grab(bbox=(490, 337, 928, 458))
words = pytesseract.image_to_string(image, lang="eng")
print(words)

运行时，倒数第二行出现如下错误。

Traceback (most recent call last):
  File "c:\Users\chad\Visual_Studio_Code\test.py", line 7, in <module>
    words = pytesseract.image_to_string(image, lang="eng")

    raise TesseractError(proc.returncode, get_errors(error_string))
pytesseract.pytesseract.TesseractError: (2, 'Usage: pytesseract [-l lang] input_file')      

我不知道发生了什么事，所以任何帮助将不胜感激。

您确定需要指定 lang="eng" 吗？默认是英文识别
