lmdb module install problem

[emre32emre]

I want to download the python lmdb module, but I constantly encounter this problem. Patch-ng module is installed. I also tried Python version 3.12 on older versions.

i'm also having this issue, when trying to install paddleocr. Had to downgrade to lower version of python, as lmdb only seems to support up to python 3.11 and I was using python 3.12. Then started facing a similar issue with PyMuPDF as well, found this link which said it only supports python 3.10. https://stackoverflow.com/questions/76379293/how-can-i-fix-the-error-in-pymupdf-when-installing-paddleocr-with-pip But tried this command from a comment pip install "paddleocr>=2.0.1" --upgrade PyMuPDF==1.21.1 and it worked on Python 3.11

py-lmdb 还没有适配 python 3.12， 请参考： https://github.com/jnwatson/py-lmdb/pull/352 里的评论，自行构建 py-lmdb 的 python 3.12 的安装包。
