我已经安装了'borb'使用pip install borb和安装后，我得到以下消息:

现在，如果我运行下面的代码，我将得到一个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()
我得到以下错误:
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)

ImportError: cannot import name 'Document' from 'borb.pdf.document' (C:UsersDELLAppDataLocalProgramsPythonPython37libsite-packagesborbpdfdocument__init__.py)
关于如何解决这个问题的任何输入…?
请从borb.pdf中导入Documentclass
用法:from borb.pdf import Document
from borb.pdf.document.document import Document
"Document"是来自borb.pdf.document.document.py的类
