I'm not certain whether the squiggle is invalid or due to the MSVC standard library headers not being error-free if compiled with C++11. But, since CL.exe does not support earlier standards than C++14, I believe you will want to set cppStandard to at least c++14. That appears to remo...

顺便说一句,我仍然不相信这比编写transform_if更好。使用Niebler的range v3,应该可以编写类似于std::vector<int> arrKeys = theMap | view :: remove_if([&](auto const& p){return p.second!= value; })| view :: keys;的代码(未经测试) - dyp...
