使用colcon构建工作区时出错
-
我在跟着例程文档使用colcon构建工作区进行学习，在进行到
colcon build时发生了如下错误：WARNING: given --rosdistro melodic but ROS_DISTRO is "humble". Ignoring environment. #All required rosdeps installed successfully yyh@yyh-device:~/ros_dev_ws$ colcon build [0.193s] WARNING:colcon.colcon_core.package_selection:Some selected packages are already built in one or more underlay workspaces: 'turtlesim' is in: /opt/ros/humble If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time. If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur. If you understand the risks and want to override a package anyways, add the following to the command line: --allow-overriding turtlesim This may be promoted to an error in a future release of colcon-override-check.

在不加入turtlesim时使用空文件colcon build成功
请问这种情况该怎么解决？

@280390510 在 使用colcon构建工作区时出错 中说：
given --rosdistro melodic but ROS_DISTRO is "humble" 是不是bashrc有什么配置错误的地方
