我需要在dolphinbdb中调用一个自己写的python函数，这个函数调用了pands和numpy，在dolphindb里重新实现工作量太大，于是就想编译官方的插件帮助，结果一直编译出错。

具体错误如下:

在执行完cmake -DPYTHON:STRING=3.7 ../ -G "MinGW Makefiles"之后，执行mingw32-make -j4，显示：

D:\DolphinDBPlugin\DolphinDBPlugin-master\py\build>mingw32-make -j4

mingw32-make[2]: *** No rule to make target '../bin/windows/python37.dll', needed by 'libPluginPy.dll'.  Stop.

mingw32-make[2]: *** Waiting for unfinished jobs....

mingw32-make[1]: *** [CMakeFiles\Makefile2:99: CMakeFiles/PluginPy.dir/all] Error 2

mingw32-make: *** [Makefile:90: all] Error 2

这个问题我直接把python37.dll拷贝到了报错的位置上../bin/windows/python37.dll，然后似乎解决掉了，再次执行mingw32-make -j4

报错信息：

D:\DolphinDBPlugin\DolphinDBPlugin-master\py\build>mingw32-make -j4

到这实在是不懂了，有没有大哥来教一下这是啥情况
