The following code does not compile:

#include <vector>
#include <span>
#include <https://raw.githubusercontent.com/martinmoene/span-lite/master/include/nonstd/span.hpp>

#define s nonstd::span
// #define s std::span

void consume(s<int>);

int main () {
    std::vector a{1, 2, 3};

    consume(s(a.begin() + 1, a.end()));
}

"The following code does not compile" seems to hold for both std::span and nonstd::span, see this code at godbolt.
