FileNotFoundError: [Errno 2] No such file or directory: ‘tesseract’
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 config=config) File "/usr/local/lib/python3.5/dist-packages/pytesseract/pytesseract.py", line 94, in run_tesseract stderr=subprocess.PIPE) File "/usr/lib/python3.5/subprocess.py", line 947, in __init__ restore_signals, start_new_session) 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

tips
此处是在Ubuntu 16.04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。：）
