vnpy_ctp源码下载后转变为python可用的处理过程
目录
写在前面
window系统中必须安装有Visual Studio ,后面源码安装时需要进行C++编译
下载源码并解压
GitHub - vnpy/vnpy_ctp: VeighNa框架的CTP交易接口
下载zip压缩包
解压
要在python中能执行，要有.pyd文件，解压后的文件夹内没有.pyd文件
创建python项目
新建一个python项目，项目在一个新的虚拟环境中执行。
环境
操作系统：window10 64位
开发工具：pycharm
python版本：python3.8.10
过程
编译vnpy_ctp源码
打开项目下方的terminal面板
cd 到解压后setup.py 所在文件夹
执行 python setup.py build
大概2到3分钟，编译完毕，在setup.py所在文件夹下多出一个build文件夹
在build下找到与操作系统和python版本对应的文件夹，以本文为例，操作系统是64位，那文件夹名称中就会有amd64,python版本3.8，文件夹名称中就会包含3.8，所以本文的文件夹名为lib.win-amd64-3.8
我们需要的是 build>lib.win-amd64-3.8>vnpy_ctp文件夹下的api文件夹，我们把api文件夹复制到项目目录下
验证可用性
创建Md调用的类和Td调用的类
