Could not build wheels for lanms-neo, which is required to install pyproject.toml-based projects
我没有使用pip install paddleocr
而是去下载Github上的PaddleOCR项目
PaddleOCR V2.6
然后进入项目执行命令时
pip install -r requirements.txt -i https://mirror.baidu.com/pypi/simple
到了安装lanms-neo，报错，并且提示Microsoft Visual C++ 14.0 的环境问题

单独安装一样报错pip install lanms-neo==1.0.2 -i https://pypi.tuna.tsinghua.edu.cn/simple
然后找了论坛上的solved_packageMissInInstalling_mu_visual_cpp_build_tools_2015_update_3_x64_dvd_dfd9a39c.iso
安装，但是没有成功，提示需要更高的版本
lanms.cpp
