OpenCV面临一个错误，即使在安装后也找不到tesseract moule
pip安装tesseract
opencv重新安装也完成了，但它不会工作。
opencv安装命令包括
pip安装opencv-python
pip安装打开控件-Python
使用此github指南安装tesseract.exe-link
我仍然面临以下错误
错误-未找到tesseract模块

修复此错误后，将文件路径（C：\Program Files（x86）\Tesseract-OCR\tesseract.exe）更改为-〉（C：\Program Files\Tesseract-OCR\tesseract.exe），工作正常
无论您在windows中的路径是什么programfiles，都不要使用**Program Files（x86）**它不会工作
仍然显示或不安装错误，你面临的，然后按Windows + R键，并运行您的文件路径（C：\Program Files\Tesseract-OCR\Tesseract.exe）它会为我工作，
