3. 运行结果、错误截图

4. 我尝试过的解决方法和结果

5. 我想要达到的结果

【运行环境】

硬件：rk3568 ROM版本：4.0 DevEvoStudio版本： SDK版本：

请问您解决了这个问题吗？我也遇到了类似的

回复 creamli: 也还没有解决呢

回复 shixiaocheng: 请问下您解决了这个问题么？

据我所知sdk_info.json文件是OpenHarmony中的一个关键配置文件，它的作用是定义项目的SDK信息，包括依赖的模块、版本、构建选项等，如果缺少或配置错误的sdk_info.json文件会导致编译过程出错，它的配置主要是使用JSON格式指定项目依赖的模块和版本。

是不是preinstall少装东西了，重新运行下呢

回复 深开鸿_王石: 应该不是，我是编写了一个程序，调用了GPIO，然后编译过程报了这些问题。

请问现在作者已经解决这个问题了么？
