我正在学习ROS2 foxy，我对colcon构建没有什么问题。
我只是制作了没有包的colcon_ws。当我尝试构建时，会显示一些错误消息。以下是我所做的。
$ mkdir colcon_ws
$ cd colcon_ws
$ colcon build
错误信息在这里。另外，奇怪的是出现了错误消息，但是构建成功了。

我该如何修复它?
检查colcon-core版本:colcon version-check
查看colcon-core是否是最新的。如果不是最新的，请通过以下方式更新:
sudo apt update
sudo apt install python3-colcon-common-extensions
sudo apt install python3-colcon-core
