ros2 foxy 自定义消息接口编译 “没有规则可制作目标”

@87725837 你的构建命令是在哪一个目录下运行的
-
@小鱼 工作空间下运行的
oem@oem-ThinkPad-X1-Yoga-3rd:~/town_ws$ colcon build --packages-select village_interfaces Starting >>> village_interfaces --- stderr: village_interfaces make[1]: *** 没有规则可制作目标“village_interfaces__py/CMakeFiles/village_interfaces__py.dir/all”，由“CMakeFiles/village_interfaces__python.dir/all” 需求。 停止。 make[1]: *** 正在等待未完成的任务.... make: *** [Makefile:146：all] 错误 2 --- Failed <<< village_interfaces [0.12s, exited with code 2] Summary: 0 packages finished [0.50s] 1 package failed: village_interfaces 1 package had stderr output: village_interfaces -
@87725837 排除一些环境因素先，可以尝试在root下构建：
在oem@oem-ThinkPad-X1-Yoga-3rd:~/town_ws$目录下执行如下命令：
sudo su
source /opt/ros/foxy/setup.bash
rm -rf build install log
colcon build -
@小鱼
结果如下：oem@oem-ThinkPad-X1-Yoga-3rd:~/town_ws$ sudo su [sudo] oem 的密码： root@oem-ThinkPad-X1-Yoga-3rd:/home/oem/town_ws# source /opt/ros/foxy/setup.bash root@oem-ThinkPad-X1-Yoga-3rd:/home/oem/town_ws# rm -rf build/ install/ log/ root@oem-ThinkPad-X1-Yoga-3rd:/home/oem/town_ws# colcon build Starting >>> village_interfaces Starting >>> village_li Starting >>> village_wang Finished <<< village_li [1.37s] --- stderr: village_interfaces make[1]: *** 没有规则可制作目标“village_interfaces__py/CMakeFiles/village_interfaces__py.dir/all”，由“CMakeFiles/village_interfaces__python.dir/all” 需求。 停止。 make[1]: *** 正在等待未完成的任务.... make: *** [Makefile:146：all] 错误 2 --- Failed <<< village_interfaces [2.91s, exited with code 2] Aborted <<< village_wang [8.64s] Summary: 1 package finished [9.06s] 1 package failed: village_interfaces 1 package aborted: village_wang 1 package had stderr output: village_interfaces root@oem-ThinkPad-X1-Yoga-3rd:/home/oem/town_ws#自定义消息的包还是一样的报错

@87725837 尝试开一个新的工作空间，下载我的代码，进行构建测试，再排除下代码问题，代码地址：https://github.com/fishros/ros2_town

@小鱼 结果如下：

oem@oem-ThinkPad-X1-Yoga-3rd:~/ros2_town$ colcon build可以确定是环境问题了，应该和你混装ros和ros2造成的，请附上你的 ～/.bashrc 文件内容，进一步检查环境。

请去掉这句后再次测试，这是ros1的命令，可能会环境变量产生很大影响

还是不行
