@847718956 搞定了，更新了代码，已有工程解决方案如下：

打开工程，删除目录.pio/libdeps/featheresp32/micro_ros_platformio

接着重新点击编译即可。

机器人小伊

从你的报错信息来看，应该是你没有安装 Adafruit_GFX.h 的依赖。你可以使用 platformio lib 命令来查找并安装这个依赖，然后重新编译你的代码，就可以解决问题了。

以上为生成回答，仅供参考～

从上面的报错信息可以看出，缺少Adafruit_I2CDevice.h文件，可以在PlatformIO库中搜索，然后下载安装对应的库文件，或者在Github上找到对应的文件，然后添加到项目中即可。

@小鱼我根据这篇CSDN的步骤添加Adafruit BusIO依赖库

lib_deps = 
	https://gitee.com/ohhuo/micro_ros_platformio.git
	adafruit/Adafruit SSD1306@^2.5.7
	adafruit/Adafruit BusIO@^1.14.1```

删除.pio/libdeps/featheresp32/micro_ros_platformio/libmicroros文件夹

不是pio/libdeps/featheresp32/micro_ros_platformio文件夹，这样文件会在重新编译后重新生成该文件

重新编译出现下面问题

@小鱼这里下载太慢了。挂梯子也一样

1991623683

有一个问题，用git 克隆代码，编译出现错误： 15795905-ed0a-427c-8303-868a76c3aa1b-图片.png ，请问是什么问题

小鱼

@1991623683 有重新编译过吗，删掉libmicroros

likesingjumprap

该贴中的方法都试过了还是不行，有兄弟们解决了的吗，
platformio.ini，因为报错，根据提示也加了很多依赖，还是不行

@842145248 你的报错是什么

@小鱼刚刚重新编译了下，好慢，麻烦大佬帮我看看

@842145248 是 src/main.cpp ，你的错误在 main函数里不是自定义功能包造成的

likesingjumprap

@小鱼感谢大佬的的回复，我补充完整了main.cpp后可以编译了，我按照教程还没到编写main.cpp，我以为不用先写main.cpp ，编译看看是否有错

但是命令行调用服务时出现了类似这种导包问题：重新运行代码时出现：UnsupportedTypeSupport: Could not import 'rosidl_typesupport_c' for package 'village_interfaces'， CMakelist.txt 和 packages.xml，看着好像都没问题，麻烦大佬再帮我看看
