**Steps to reproduce the behavior:**

1.sudo n lts
2.npm i apache-rocketmq --rebuild

**Expected behavior**

install success

## Context

- **Node Version**: v12.16.2
- **SDK Version**: 1.0.0-rc1
- **Platform**: macos

检查 src/rocketmq.cpp 第 42 行附近失败的调用，以及 script/download_lib.js 中的安装流程。使用 Node v12.16.2 运行 npm i apache-rocketmq --rebuild 进行复现，并确认 node-gyp 能够完成且软件包能够在 macOS 上成功安装。
