Tesseract python3 錯誤：tesseract is not installed or it's not in your path

1. 系統：Mac os x  
2. 工具：PyCharm
3. Python：3.7

錯誤：

pytesseract.pytesseract.TesseractNotFoundError: tesseract is not installed or it's not in your path

 

原因：

pytesseract 在調用的tesseract的時候沒有找到對應的執行文件

 

我的解決方法：

在終端輸入命令：brew list tesseract

會看到如下的信息：/usr/local/Cellar/tesseract/4.0.0_1/bin/tesseract

修改：
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pytesseract/pytesseract.py", line 186, in run_tesseract

# CHANGE THIS IF TESSERACT IS NOT IN YOUR PATH, OR IS NAMED DIFFERENTLY
修改地方：tesseract_cmd = 'tesseract'
修改爲  ：tesseract_cmd = '/usr/local/Cellar/tesseract/4.0.0_1/bin/tesseract‘
