 4. 运行爬虫程序
 
    ```shell
-   python main.py --platform xhs --lt qrcode
+   # 从配置文件中读取关键词搜索相关的帖子并爬去帖子信息与评论
+   python main.py --platform xhs --lt qrcode --type search
+   
+   # 从配置文件中读取指定的帖子ID列表获取指定帖子的信息与评论信息
+   python main.py --platform xhs --lt qrcode --type detail
    ```
 
 5. 打开对应APP扫二维码登录
 
 6. 等待爬虫程序执行完毕，数据会保存到 `data/xhs` 目录下
 
+## 常见程序运行出错问题
+```shell
+# Q: 爬去抖音报错: `execjs._exceptions.ProgramError: SyntaxError: 缺少 ';'`
+# A: 该错误为缺少 nodejs 环境这个错误安装 nodejs 环境即可，版本为：`v16.8.0`
+
+# Q: 可以指定关键词爬取吗？
+# A: 在config/base_config.py 中 KEYWORDS 参数用于控制需要爬去的关键词
+
+# Q: 可以指定帖子爬去吗？
+# A：在config/base_config.py 中 SPECIFIED_ID_LIST 参数用于控制需要指定爬去的帖子ID列表
+
+# Q: 刚开始能爬取数据，过一段时间就是失效了？
+# A：出现这种情况多半是由于你的账号触发了平台风控机制了，❗️❗️请勿大规模对平台进行爬虫，影响平台。
