    const { body } = meriyah.parseScript(str, { next: true, module });

    walk(body, {
        enter(node) {
            // console.log(JSON.stringify(node, null, 2));
            // console.log("-------------------------");
            try {
                if (!module && (helpers.isRequireStatment(node) || helpers.isRequireResolve(node))) {
                    const arg = node.arguments[0];
                    if (arg.type === "Identifier") {
                        if (identifiers.has(arg.name)) {
                            dependencies.add(identifiers.get(arg.name));
