我想使用 Pybind11 或直接使用 Python C API 將此 Python 代碼轉換為 C++ 代碼：import astcode = "print('Hello World!')"code_ast = ast.parse(code, mode="exec") # "code" being a string containing code# ... perform some modifications on "code_ast"exec(compile(code_ast, filename="<ast>", mode="exec"))這是我目前使用 Pybind11 的內容：#include <iostream>#include "pybind11/embed.h"namespace py = pybind11;std::string code = "print('Hello World!')";py::module ast = py::module::import("ast");py::module builtins = py::module::import("builtins");py::object code_ast = ast.attr("parse")(code, "<unknown>", "exec");// ... perform some modifications on "code_ast"py::object compiled_code = builtins.attr("compile")(code_ast, "<ast>", "exec");builtins.attr("exec")(compiled_code);不幸的是，最后一行 C++ 代碼引發了一個運行時錯誤：SystemError: frame does not exist.我不確定我是否理解此錯誤，我嘗試將globals和傳遞locals給exec，但沒有解決問題。編輯：通過時globals，它說：SystemError: <built-in function globals> returned NULL without setting an error關于如何正確實現這一目標的任何想法？
