我已经使用安装了tasseract
pip install pytesseract
每当我尝试运行这段代码
from PIL import Image
import pytesseract
im = Image.open('hasan1.jpg')
print (pytesseract.image_to_string(im))
我得到这些错误。

我相信PyTesseract要求您在系统上安装tesseract库-PyTesseract正在尝试运行命令行界面，但大概找不到它，因为您仅安装了python绑定。
如果您使用的是基于Ubuntu / Debian的系统，则可以尝试：
sudo apt-get install tesseract-ocr
您可以查看Tesseract安装文档以获取更多信息：https : //github.com/tesseract-ocr/tesseract/wiki
