pytesseract安装问题- Linux mint

Question

我执行了pytesseract的安装来从图像中提取文本，但是我的代码有一个我无法解决的问题，我已经查看了几个站点寻找错误的来源，但我仍然有问题……在错误消息中，它说没有安装tesseract，或者在路径中没有安装，但是我检查了与错误消息相同的目录，并且文件就在那里！

业务系统：

Linux 20.3肉桂

Python: 3.9

代码：

import cv2
import pytesseract

img = cv2.imread("./Desktop/screenshot.png")
text = pytesseract.image_to_string(img)
print(text)

错误：

/usr/bin/python3.9 /home/alex/PycharmProjects/Kbot/main.py
Traceback (most recent call last):
  File "/home/alex/.var/app/com.jetbrains.PyCharm-Community/data/python/lib/python3.9/site-packages/pytesseract/pytesseract.py", line 255, in run_tesseract

During handling of the above exception, another exception occurred:

你可能检查过那里有一个文件"/home/alex/.var/app/com.jetbrains.PyCharm-Community/data/python/lib/python3.9/site-packages/pytesseract/pytesseract.py“，但是.pytesseract.py只是一个围绕您需要安装的tesseract引擎的包装器，以便pytesseract能够使用它。

使用安装tesseract

或在命令行中使用

$ sudo apt install tesseract-ocr -y
