解决方法

先查看pip支持的版本

C:\Users\hasee>python
Python 3.6.1 (v3.6.1:69c0db5, Mar 21 2017, 17:54:52) [MSC v.1900 32 bit (Intel)] on win32

>>> exit()

在https://github.com/simonflueckiger/tesserocr-windows_build/releases这里下载对应pip版本的tesserocr，然后安装

D:\ProgramFiles\Development\Python>pip3 install tesserocr-2.4.0-cp36-cp36m-win32.whl
Processing d:\programfiles\development\python\tesserocr-2.4.0-cp36-cp36m-win32.whl
Installing collected packages: tesserocr

2、导入PIL报没有模块

D:\ProgramFiles\Development\Python>python

>>> import tesserocr
>>> from PIL import Image
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named ‘PIL‘

解决方法

在https://www.lfd.uci.edu/~gohlke/pythonlibs/#pillow这个网站上下载对应pip版本的pillow，然后安装

D:\ProgramFiles\Development\InternetWrom\download>pip install Pillow-6.1.0-cp36-cp36m-win32.whl
Processing d:\programfiles\development\internetwrom\download\pillow-6.1.0-cp36-cp36m-win32.whl

3、RuntimeError: Failed to init API, possibly an invalid tessdata path:

C:\Users\hasee>python

  File "tesserocr.pyx", line 2443, in tesserocr._tesserocr.image_to_text
RuntimeError: Failed to init API, possibly an invalid tessdata path: D:\ProgramFiles\Development\Python\Python36\Scripts/

解决方法

Path中添加 D:\ProgramFiles\Development\InternetWrom\Tesseract-OCR\Tesseract-OCR

新建变量名--TESSDATA_PREFIX 
变量值--D:\ProgramFiles\Development\InternetWrom\Tesseract-OCR\tessdata
