下载此https://github.com/pybind/pybind11/archive/v2.2.3.zip后 并创建一个简单的cpp文件:
#include <pybind11/pybind11.h>
int add(int i, int j) { return i + j; }
PYBIND11_MODULE(example, m) {
m.doc() = "pybind11 example plugin"; // optional module docstring
m.def("add", &add, "A function which adds two numbers");
}

我收到此错误
Error C2446 '<': no conversion from 'unsigned __int64' to 'unsigned __int64 *' in c:\program files (x86)\microsoft visual studio\2017\professional\vc\tools\msvc\14.14.26428\include\vector line 2326
有人会知道这可能是指什么,可能还有如何修复它?

这似乎是与
相关的VS 2017问题categoriesSelected: Set<Category>;
// bind this method with the template [checked]='category'
isSelected(category) {
return this.categoriesSelected.has(category);
}
