关于mac上成功安装vnpy_ctp后动态链接库 .framework 没有被正确加载的问题解决方案 - 主题

在 MacOS 上使用 Anaconda 安装 vn.py 框架及其 CTP 接口模块 vnpy_ctp 时，虽然 pip 显示模块已安装成功，但在pycharm中导入模块时却出现如下报错：

Unresolved reference 'vnpy_ctp'

于是我在终端进行该包的导入：

python -c "import vnpy_ctp; print(vnpy_ctp.__file__)"

结果显示如下：

Traceback (most recent call last):

可以看到我的.so文件确实内嵌了一个路径：

@rpath/thostmduserapi_se.framework/Versions/A/thostmduserapi_se

而我的文件又确实放在目录下

/Users/zohix/Zohix/Code/Pycharm/量化/vnpy-4.1.0/github/vnpy_ctp/vnpy_ctp/api/thostmduserapi_se.framework

所以可能是 @rpath 未正确配置的问题

因此这里我进入vnpy_ctp目录的.vnpy_ctpapi目录下

cd /Users/zohix/Zohix/Code/Pycharm/量化/vnpy-4.1.0/github/vnpy_ctp/.vnpy_ctpapi

将完整的 @rpath 分别添加到vnctpmd以及vnctptd的.so文件：

install_name_tool -add_rpath /Users/zohix/Zohix/Code/Pycharm/量化/vnpy-4.1.0/github/vnpy_ctp/vnpy_ctp/api vnctpmd.cpython-310-darwin.so
install_name_tool -add_rpath /Users/zohix/Zohix/Code/Pycharm/量化/vnpy-4.1.0/github/vnpy_ctp/vnpy_ctp/api vnctptd.cpython-310-darwin.so

（此时可能还要打开一下这两个动态链接库文件，但是在我的mac上是不用的）

此时再次运行

python -c "import vnpy_ctp; print(vnpy_ctp.__file__)"

则能够正确导出正确的路径

/Users/zohix/Zohix/Code/Pycharm/量化/vnpy-4.1.0/github/vnpy_ctp/vnpy_ctp/__init__.py

在pycharm中执行main即可运行（可能还是会有警告，但是无伤大雅...
