解决方法

先查看pip支持的版本

C:Usershasee>python
Python 3.6.1 (v3.6.1:69c0db5,Mar 21 2017,17:54:52) [MSC v.1900 32 bit (Intel)] on win32
Type "help","copyright","credits" or "license" for more information.
>>> import pip
>>> import pip._internal
>>> print(pip._internal.pep425tags.get_supported())
[(‘cp36‘,‘cp36m‘,‘win32‘),(‘cp36‘,‘none‘,(‘py3‘,‘any‘),(‘cp3‘,(‘py36‘,(‘py35‘,(‘py34‘,(‘py33‘,(‘py32‘,(‘py31‘,(‘py30‘,‘any‘)]
>>> 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:ProgramFilesDevelopmentPython>pip3 install tesserocr-2.4.0-cp36-cp36m-win32.whl
Processing d:programfilesdevelopmentpythontesserocr-2.4.0-cp36-cp36m-win32.whl
Installing collected packages: tesserocr
Successfully installed tesserocr-2.4.0

?

2、导入PIL报没有模块

D:ProgramFilesDevelopmentPython>python
Python 3.6.1 (v3.6.1:69c0db5,"credits" or "license" for more information.
>>> import tesserocr
>>> from PIL import Image
Traceback (most recent call last):
  File "<stdin>",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:ProgramFilesDevelopmentInternetWromdownload>pip install Pillow-6.1.0-cp36-cp36m-win32.whl
Processing d:programfilesdevelopmentinternetwromdownloadpillow-6.1.0-cp36-cp36m-win32.whl
Installing collected packages: Pillow
Successfully installed Pillow-6.1.0

测试

D:ProgramFilesDevelopmentInternetWromTest>python
Python 3.6.1 (v3.6.1:69c0db5,"credits" or "license" for more information.
>>> import tesserocr
>>> from PIL import Image

?

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

C:Usershasee>python
Python 3.6.1 (v3.6.1:69c0db5,"credits" or "license" for more information.
>>> import tesserocr
>>> from PIL import Image
>>> img = Image.open(‘D:ProgramFilesDevelopmentInternetWromTestimage.png‘)
>>> print(tesserocr.image_to_text(img))
Traceback (most recent call last):
  File "<stdin>",in <module>
  File "tesserocr.pyx",line 2443,in tesserocr._tesserocr.image_to_text
RuntimeError: Failed to init API,possibly an invalid tessdata path: D:ProgramFilesDevelopmentPythonPython36Scripts/

解决方法

Path中添加 D:ProgramFilesDevelopmentInternetWromTesseract-OCRTesseract-OCR

新建变量名--TESSDATA_PREFIX 
变量值--D:ProgramFilesDevelopmentInternetWromTesseract-OCRtessdata
