报错FileNotFoundError: [Errno 2] No such file or directory

报错问题如下：

Traceback (most recent call last):

File "identCode.py", line 36, in <module>

print(getCode(sys.argv[1]))

File "identCode.py", line 25, in getCode

vcode = pytesseract.image_to_string(image)

File "/usr/local/lib/python3.5/dist-packages/pytesseract/pytesseract.py", line 161, in image_to_string

File "/usr/lib/python3.5/subprocess.py", line 1551, in _execute_child

raise child_exception_type(errno_num, err_msg)

FileNotFoundError: [Errno 2] No such file or directory: 'tesseract'

 

解决方案：

安装tesseract

sudo apt install tesseract

此处是在ubuntu16.04上出现问题然后解决了。

我之前是在win7下尝试过，相同的代码，总是报错。那么举一反三推测一下，win7下也应当安装tesseract。虽然在win7下安装tesseract之后直接cmd就可以用tesseract命令识别，而且安装的过程极为冗长而且会报错。带了n多语言的库，比如c、Perl、lua等等。以保险起见，windows系列os下要用pytesseract还是将tesseract加以安装。否则可能会有未可知的错误。
