Windows环境下无法安装PaddleOCR的问题求助

我正按照PaddleOCR的快速开始指南安装PaddleOCR包，执行命令：

pip install "paddleocr>=2.0.1" # Recommend to use version 2.0.1+

时，构建Polygon3 wheel出现如下错误：

当前使用环境：Python 3.7 的 conda 环境。

方法1：安装C++编译工具链 #

直接解决编译依赖问题：

• 下载并运行Microsoft C++ Build Tools安装程序
• 在安装界面勾选**"Desktop development with C++"**组件（包含VC++ 14.0及以上编译工具）
• 安装完成后重启终端，重新执行PaddleOCR的安装命令

方法2：安装预编译的Polygon3包 #

跳过编译步骤，直接安装适配环境的预编译wheel：

1. 激活conda环境后执行：

pip install Polygon3==3.0.9.post1 --only-binary :all:

2. 完成后再执行PaddleOCR安装命令：

pip install "paddleocr>=2.0.1"

方法3：使用conda安装Polygon3 #

利用conda的预编译包生态：

conda install -c conda-forge polygon3

安装完成后再执行PaddleOCR的安装命令。
