at /opt/ros/noetic/share/catkin/cmake/catkin_package.cmake:108 (message): catkin_package() called with unused arguments: 2

这个错误信息是由于在调用catkin_package()函数时传递了不被使用的参数2。catkin_package()函数用于定义ROS软件包的信息和依赖关系。

要解决这个问题，你可以检查你的CMakeLists.txt文件中是否在调用catkin_package()时传递了正确的参数。确保只传递被支持的参数，例如PACKAGE_NAME、CATKIN_DEPENDS等。如果你不需要这个参数，可以直接删除它。然后重新编译你的软件包，应该就能解决这个问题了。

CMake Error at /opt/ros/noetic/share/catkin/cmake/stamp.cmake:10 (configure_file): configure_file Problem configuring file Call Stack (most recent call first): /opt/ros/noetic/share/catkin/cmake/catkin_package_xml.cmake:72 (stamp) /opt/ros/noetic/share/catkin/cmake/catkin_package_xml.cmake:50 (_catkin_package_xml) /opt/ros/noetic/share/catkin/cmake/catkin_package.cmake:99 (catkin_package_xml) CMakeLists.txt:10 (catkin_package)

这个错误表明在你的CMakeLists.txt文件中有一个问题，导致无法正确配置'/opt/ros/noetic/share/catkin/cmake/stamp.cmake'文件。要解决这个问题，你可以尝试以下几个步骤：

1. 确保你的package.xml文件中正确地列出了'catkin'作为buildtool依赖项。修改package.xml文件并确保以下行存在：

<buildtool_depend>catkin</buildtool_depend>

2. 确保你的CMakeLists.txt文件中正确地使用了catkin_package()函数，并传递了正确的参数。确保以下行存在，并使用你的项目信息替换占位符：

catkin_package(
  ...
)

3. 如果你已经尝试了上述步骤但仍然遇到问题，可能是由于其他CMake配置错误导致的。请仔细检查你的CMakeLists.txt文件，并确保没有其他语法或配置错误。

如果你仍然无法解决问题，建议提供更多的错误详细信息和相关的CMakeLists.txt内容，这样我就可以更好地帮助你解决问题。

这个错误是因为您缺少了catkin_pkg模块。您需要安装catkin_pkg模块并将其添加到PYTHONPATH中。您可以通过以下命令安装它：

pip install catkin_pkg

然后，将以下命令添加到您的.bashrc文件中，将catkin_pkg添加到PYTHONPATH中：

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages:/home/k/.local/lib/python3.8/site-packages:/opt/ros/noetic/lib/python3/dist-packages

请将上述命令中的路径更改为您计算机上实际安装的catkin_pkg模块的路径。完成后，重新启动终端并尝试重新构建您的代码。
