首先：安装依赖包PIL

pip install pillow

pip3 install pillow

接着：安装tesseract

pip install tesseract

pip3 install tesseract

或者：安装pytesseract

pip install pytesseract

pip3 install pytesseract

最后：安装tesseract-data

配置：环境变量

vim ~/.bash_profile

添加如下环境变量，TESSDATA_PREFIX的值根据tesseract的安装路径做调整

export TESSDATA_PREFIX="/usr/share/tessdata"
export PATH=$PATH:$TESSDATA_PREFIX
1
2
使环境变量生效

source ~/.bash_profile
例程：

1 import pytesseract
2 #tesseract_cmd = '/usr/bin/tesseract'
3 pytesseract.pytesseract.tesseract_cmd = '/usr/bin/tesseract'
4 from PIL import Image
5  
6 image = Image.open("/home/nication/python/code.jpg")
7 code = pytesseract.image_to_string(image)
8 print(code)

python testp.py  
6067

结果没有问题
