#### 解决pytesseract.pytesseract.TesseractError: (1, ‘Error opening data file C:\\Program Files\\Tesseract-OCR\\tessdata/chi\_sim.traineddata Please make sure the TESSDATA\_PREFIX environment variable is set to your “tessdata” directory. Failed loading language ‘chi\_sim’ Tesseract couldn’t load any languages! Could not initialize tesseract.’) ####

#### 报错信息 ####

pytesseract.pytesseract.TesseractError: (1, 'Error opening data file C:\\Program Files\\Tesseract-OCR\\tessdata/chi_sim.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory. Failed loading language \'chi_sim\' Tesseract couldn\'t load any languages! Could not initialize tesseract.')

#### 解决办法 ####

path = "img\\text-img.png"
    
    testdata_dir_config = '--tessdata-dir "C:\\ProgramFiles\\Tesseract-OCR\\tessdata"'
    
    textCode = pytesseract.image_to_string(Image.open(path),config=testdata_dir_config,lang='chi_sim')

#### 若不能使用，配置环境变量 ####

TESSERAC-OCR
    C:\Program Files\Tesseract-OCR\tessdata

### TESSERAC-OCR安装 ###

#### 一、安装python模块 ####

pip3 install pytesseract

#### 二、安装tesseract orc ####

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

#### 三、配置tesseract运行文件 ####

...\Python36\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'
