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

@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
-
@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$ source install/setup.bash && ros2 service call /oled_control fishbot_interfaces/srv/OledControl "{px: 0, py: 0, data: 'nihao'}" Traceback (most recent call last): File "/opt/ros/humble/local/lib/python3.10/dist-packages/rosidl_generator_py/import_type_support_impl.py", line 46, in import_type_support return importlib.import_module(module_name, package=pkg_name) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1004, in _find_and_load_unlocked ModuleNotFoundError: No module named 'fishbot_interfaces.fishbot_interfaces_s__rosidl_typesupport_c' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/opt/ros/humble/bin/ros2", line 33, in <module> sys.exit(load_entry_point('ros2cli==0.18.7', 'console_scripts', 'ros2')()) File "/opt/ros/humble/lib/python3.10/site-packages/ros2cli/cli.py", line 89, in main rc = extension.main(parser=parser, args=args) File "/opt/ros/humble/lib/python3.10/site-packages/ros2service/command/service.py", line 41, in main return extension.main(args=args) File "/opt/ros/humble/lib/python3.10/site-packages/ros2service/verb/call.py", line 58, in main return requester( File "/opt/ros/humble/lib/python3.10/site-packages/ros2service/verb/call.py", line 86, in requester cli = node.create_client(srv_module, service_name) File "/opt/ros/humble/local/lib/python3.10/dist-packages/rclpy/node.py", line 1413, in create_client check_is_valid_srv_type(srv_type) File "/opt/ros/humble/local/lib/python3.10/dist-packages/rclpy/type_support.py", line 51, in check_is_valid_srv_type check_for_type_support(srv_type) File "/opt/ros/humble/local/lib/python3.10/dist-packages/rclpy/type_support.py", line 29, in check_for_type_support msg_or_srv_type.__class__.__import_type_support__() File "/home/nzb/vscode_project/cplus_demo/ros2_demo/chat13/example14_custom_interfaces/extra_packages/install/fishbot_interfaces/local/lib/python3.10/dist-packages/fishbot_interfaces/srv/_oled_control.py", line 303, in __import_type_support__ module = import_type_support('fishbot_interfaces') File "/opt/ros/humble/local/lib/python3.10/dist-packages/rosidl_generator_py/import_type_support_impl.py", line 48, in import_type_support raise UnsupportedTypeSupport(pkg_name) rosidl_generator_py.import_type_support_impl.UnsupportedTypeSupport: Could not import 'rosidl_typesupport_c' for package 'fishbot_interfaces'main.cpp

这句在哪一个目录下执行的
-
@小鱼
example14_custom_interfaces/extra_packages目录下 -
@842145248 删除掉build和install ，重新colcon build后测试，还报错就贴一下 CMakeLists.txt 和 srv文件
-
@小鱼 删除重新编译后还不行
