无法在 Mac 上安装 Tesseract-OCR [英] Can't install Tesseract-OCR on Mac

问题描述

我正在尝试使用 pytesseract 在 python 2.7.14 中制作 OCR 程序.当我运行我的代码时:

I'm trying to make an OCR program in python 2.7.14 with pytesseract. When I ran my code:

from PIL import Image
import pytesseract

print(pytesseract.image_to_string(Image.open('test.png')))

我收到错误:

IOError: [Errno 2] No such file or directory: 'test.png'

找了很多地方，好像需要安装tesseract-ocr.我跑了:

I searched in many places, and it seems that I need to install tesseract-ocr. I ran:

pip install tesseract-ocr

但是我得到了错误:

无论如何我可以解决这个问题吗?(当我尝试其他安装方式时出现同样的错误，比如 sudo)

Is there anyway I can fix this? (This same error occurred when I tried other ways of installing it, like sudo)

推荐答案

您需要安装 tesseract 本身.

You need to install the tesseract itself.

正如它在文档中所说的那样https://github.com/tesseract-ocr/tesseract/wiki#homebrew

As it says in documentation https://github.com/tesseract-ocr/tesseract/wiki#homebrew

    brew install tesseract 

另外，我也建议通过 brew 安装 python.这样你就不会污染系统python安装.

Also I'd recommend installing python through brew as well. That way you won't pollute system python installation.

而且最好也使用 virtualenv.

And it's best to use virtualenv too.
