import fitz
doc = fitz.open("my_pdf.pdf")

当我在 fitz.py 文件中查找 def open 时，我什么也没找到。 所以我理解错误但我不明白为什么我下载的文件没有这个功能？有人可以分享好文件吗？或者我错过了什么？

Answer 1

卸载并重新安装 pyMuPDF。

这个错误通常表明 init.py 没有被执行。例如当您在安装 fitz 目录并启动 python 时发生。

Answer 2

这可能是一个安装问题，看起来您的环境中已经安装了一个包 fitz，并且与 PyMuPDF 无关。

所以当PyMuPDF 调用fitz 时，它实际上可能调用了错误的fitz 包。

您可以考虑对所有依赖项进行全新安装或创建一个虚拟环境来使用PyMuPDF。

您也可以尝试将fitz 回滚到版本1.16.14
