我有一个字符串，我想将其解析为 json，但_json似乎每次都不起作用。

#include <nlohmann/json.hpp>
#include <iostream>

using nlohmann::json;

int main()
{
    // Works as expected
    json first = "[\"nlohmann\", \"json\"]"_json;
    // Doesn't work
    std::string s = "[\"nlohmann\", \"json\"]"_json;
    json second = s;
}

第一部分有效，第二部分抛出terminate called after throwing an instance of 'nlohmann::detail::type_error' what(): [json.exception.type_error.302] type must be string, but is array。
