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 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', 'win32'), ('py3', 'none', 'win32'), ('cp36', 'none', 'any'), ('cp3', 'none', 'any'), ('py36', 'none', 'any'), ('py3', 'none', 'any'), ('py35', 'none', 'any'), ('py34', 'none', 'any'), ('py33', 'none', 'any'), ('py32', 'none', 'any'), ('py31', 'none', 'any'), ('py30', 'none', '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:\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 Successfully installed tesserocr-2.4.0
2、导入PIL报没有模块
D:\ProgramFiles\Development\Python>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 tesserocr >>> from PIL import Image Traceback (most recent call last): File "", line 1, in 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 Installing collected packages: Pillow Successfully installed Pillow-6.1.0
