Pytesseract Traceback 错误

Question

我是第一次使用 Pytesseract，但遇到了问题。我假设我忽略了一些基本的东西，我还在学习 python。我在我的电脑上安装了 Tesseract-OCR，然后使用 pip install 来安装 pytesseract。我也尝试过安装枕头，但不能，因为它已经通过 pyautogui 安装了。我尝试运行下面的代码，但出现错误。

问题：我需要更改什么或如何更正此问题？

代码：

#python 3.6
from PIL import Image
import pytesseract

# --- functions ---

def get_text(image, region):
    return pytesseract.image_to_string(image.crop(region))

def get_int(image, region):
    return int(get_text(image, region).replace(',', ''))

# --- main ---

# test on screenshots: 0.jpg ... 9.jpg
for x in range(10):
    img = Image.open('screenshots/{}.jpg'.format(x))

    region = (288, 664, 487, 706)
    text = get_text(img, region)
    print('Name:', text)

    region = (8666, 871, 1036, 920)
    value = get_int(img, region)
    print('Power:', value)

    region = (1292, 466, 1420, 515)
    value = get_int(img, region)
    print('Loot #1:', value)

    region = (1292, 555, 1420, 604)
    value = get_int(img, region)
    print('Loot #2:', value)

    region = (1292, 645, 1420, 694)
    value = get_int(img, region)
    print('Loot #3:', value)

    print('-----')

对于我来说，Python 找不到 tesseract.exe。

您可能必须手动找到它并将其文件夹添加到PATH。

顺便说一句：在文件 pytesseract.py 中有一些关于 PATH 的评论
