pip install pytesseract -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

下载地址：https://github.com/UB-Mannheim/tesseract/wiki 
点击“tesseract-ocr-w64-setup-v4.0.0-beta.1.20180414.exe”

下载安装。注意：安装的时候选中中文包（安装时把所有选项都勾上）。本人安装目录：C:\Program Files\Tesseract-OCR\tessdata

使用命令，查看版本号和支持语言：
cd C:\Program Files\Tesseract-OCR  
tesseract -v tesseract --list-langs -v tesseract --list-langs　　# 查看Tesseract-OCR支持语言 

...\Lib\site-packages\pytesseract\pytesseract.py 

找到文件：tesseract_cmd = 'tesseract'
修改为：tesseract_cmd = 'C:\\Program Files\\Tesseract-OCR\\tesseract.exe'       你放tesseract.exe的路径
