您好能不能给一个 conda 环境的 yml？ 我试试

我是这样用的，注意Python版本3.9.0，平台Windows10

python -m venv .
.\Scripts\Activate.ps1
pip install pdf2zh
pdf2zh document.pdf

[Andy-AO]

刚刚发现用pyenv local 3.11.5更换版本后这个问题消除(还有其他问题，也不能正常用)，所以版本3.9.0应该是必要条件。

似乎是加密包的版本问题，这里提供了解决方案 https://forum.rasa.com/t/from-cryptography-hazmat-bindings-rust-import-importerror-dll-load-failed-while-importing-rust-the-specified-procedure-could-not-be-found/60963/1

等待 windows 机器复现后，看看 setup.py 要不要指定最低的加密包版本。
