ImportError: cannot import name 'Document' from 'borb.pdf.document

Question

我已经使用 pip install borb 安装了 'borb' 库，安装后，我收到以下消息：

现在，如果我运行截断以下代码，我将得到 ImportError:

import typing  
from borb.pdf.document import Document  
from borb.pdf.pdf import PDF  
from borb.toolkit.text.simple_text_extraction import SimpleTextExtraction  


def main():

    # variable to hold Document instance
    doc: typing.Optional[Document] = None  

    # this implementation of EventListener handles text-rendering instructions
    l: SimpleTextExtraction = SimpleTextExtraction()  

    # open the document, passing along the array of listeners
    with open("PDFs/1.pdf", "rb") as in_file_handle:
        doc = PDF.loads(in_file_handle, [l])  
  
    # were we able to read the document?
    assert doc is not None  

    # print the text on page 0
    print(l.get_text(0))  

if __name__ == "__main__":
    main()

我收到以下错误：

ImportError: cannot import name 'Document' from 'borb.pdf.document' (C:\Users\DELL\AppData\Local\Programs\Python\Python37\lib\site-packages\borb\pdf\document\__init__.py)

关于如何解决此问题的任何意见...？
