咨询下我这个是什么问题：

• Darwin mbp.local 23.4.0 Darwin Kernel Version 23.4.0: Fri Mar 15 00:19:22 PDT 2024; root:xnu-10063.101.17~1/RELEASE_ARM64_T8112 arm64
• 使用的main分支代码
• python3.12，其实python3.10也是这个错误

整体操作步骤：

1. clone仓库
2. 创建.venv
3. 安装vnpy
4. pip install -e . 安装
5. 运行run.py报错

/Users/xx/work/quant/vnpy_ctp/.venv/bin/python /Users/xx/work/quant/vnpy_ctp/script/run.py

[vnpy]

删除clone目录的dist/build/egg-info三个文件夹。

然后运行python setup.py build。

看看有没有报错？

解决方法：~/.zshrc中添加动态库地址。

export DYLD_LIBRARY_PATH=/opt/homebrew/opt/libiconv/lib:/opt/homebrew/anaconda3/lib:$DYLD_LIBRARY_PATH

[vnpy]
