您好，我试着学习如何使用 pytesseract(https://pypi.python.org/pypi/pytesseract)，所以我运行示例代码:

try:
    import Image
except ImportError:
    from PIL import Image
import pytesseract
im=Image.open('test.png')
print(pytesseract.image_to_string(im))

但是我有错误:

Traceback (most recent call last):
  File "C:/Users/K/PycharmProjects/untitled/zad1.py", line 7, in <module>
    print(pytesseract.image_to_string(im))
  File "C:\Users\K\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pytesseract-0.1.6-py3.5.egg\pytesseract\pytesseract.py", line 161, in image_to_string

    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

我的python版本是3.5，pytesseract版本是0.1.6。 我在 Windows 7 上工作。

最佳答案

我的 Ubuntu 也遇到了这个问题。感谢@Newbie，我在安装tesseract后解决了它。

sudo apt-get install tesseract-ocr
sudo apt-get install tesseract-ocr-chi-sim

好像是

sudo pip install pytesseract

只安装 python 接口(interface)而不是 tesseract 本身

以下是我的错误信息:
