# FileNotFoundError: \[WinError 2\] 系统找不到指定的文件。 #

废话不多说，上代码

from PIL import Image
    from pyocr import tesseract
    
    tesseract.TESSERACT_CMD = r'C:\Program Files\Tesseract-OCR\tesseract.exe'
    print(tesseract.image_to_string(Image.open('test.png')))

解决思路：安装完成tesseract-ocr，之后心里就有一个疑问，pyocr库如何找到tesseract-ocr引擎并调用，果然出错！！那么pyocr的tesseract库肯定有相应的类似环境变量的属性，于是

dir(tesseract)

返回结果如下：  
\[‘CharBoxBuilder’, ‘DigitBuilder’, ‘ReOpenableTempfile’, ‘TESSDATA\_EXTENSION’, ‘TESSERACT\_CMD’, ‘TesseractError’, ‘**all**’, ‘**builtins**’, ‘**cached**’, ‘**doc**’, ‘**file**’, ‘**loader**’, ‘**name**’, ‘**package**’, ‘**spec**’, ‘\_set\_environment’, ‘builders’, ‘can\_detect\_orientation’, ‘cleanup’, ‘codecs’, ‘detect\_orientation’, ‘digits\_only’, ‘g\_creation\_flags’, ‘g\_subprocess\_startup\_info’, ‘g\_version’, ‘get\_available\_builders’, ‘get\_available\_languages’, ‘get\_name’, ‘get\_version’, ‘image\_to\_string’, ‘is\_available’, ‘logger’, ‘logging’, ‘os’, ‘psm\_parameter’, ‘run\_tesseract’, ‘shutil’, ‘subprocess’, ‘sys’, ‘tempfile’\]  
找到相应属性
