ROS操作系统catkin_make后出现问题

[czhero2008]

提示出现
lol@lol-Lenovo-Product:~/catkin_ws$ catkin_make
Base path: /home/lol/catkin_ws
Source space: /home/lol/catkin_ws/src
Build space: /home/lol/catkin_ws/build

Invalid package manifest "/home/lol/catkin_ws/src/beginner_tutorials/package.xml": The manifest must contain exactly one "description" tags
最后一项Invalid package manifest,无效的程序包清单，我编译出来的程序一直没法运行，这是怎么回事？

我觉得说的很清楚了呀，你的package.xml文件不完全啊，没包含description 标签啊。<?xml version="1.0"?> <package format="2"> <name>myrobot_gazebo</name> <version>0.0.0</version> <description>The myrobot_gazebo package</description> <!-- One maintainer tag required, multiple allowed, one person per tag --> <!-- Example: --> <!-- <maintainer email="[e-mail]">Jane Doe</maintainer> --> <maintainer email="[e-mail]">siemens</maintainer> <!-- One license tag required, multiple allowed, one license per tag --> <!-- Commonly used license strings: --> <!-- BSD, MIT, Boost Software License, GPLv2, GPLv3, LGPLv2.1, LGPLv3 --> <license>TODO</license> <!-- Url tags are optional, but multiple are allowed, one per tag --> <!-- Optional attribute type can be: website, bugtracker, or repository --> <!-- Example: --> <!-- <url type="website">http://wiki.ros.org/myrobot_gazebo</url> --> <!-- Author tags are optional, multiple are allowed, one per tag --> <!-- Authors do not have to be maintainers, but could be --> <!-- Example: --> <!-- <author email="[e-mail]">Jane Doe</author> --> <!-- The *depend tags are used to specify dependencies --> <!-- Dependencies can be catkin packages or system dependencies --> <!-- Examples: --> <!-- Use depend as a shortcut for packages that are both build and exec dependencies --> <!-- <depend>roscpp</depend> --> <!-- Note that this is equivalent to the following: --> <!-- <build_depend>roscpp</build_depend> --> <!-- <exec_depend>roscpp</exec_depend> --> <!-- Use build_depend for packages you need at compile time: --> <!-- <build_depend>message_generation</build_depend> --> <!-- Use build_export_depend for packages you need in order to build against this package: --> <!-- <build_export_depend>message_generation</build_export_depend> --> <!-- Use buildtool_depend for build tool packages: --> <!-- <buildtool_depend>catkin</buildtool_depend> --> <!-- Use exec_depend for packages you need at runtime: --> <!-- <exec_depend>message_runtime</exec_depend> --> <!-- Use test_depend for packages you need only for testing: --> <!-- <test_depend>gtest</test_depend> --> <!-- Use doc_depend for packages you need only for building documentation: --> <!-- <doc_depend>doxygen</doc_depend> --> <buildtool_depend>catkin</buildtool_depend> <build_depend>cv_bridge</build_depend> <build_depend>rospy</build_depend> <build_depend>sensor_msgs</build_depend> <build_depend>std_msgs</build_depend> <build_depend>tf</build_depend> <build_export_depend>cv_bridge</build_export_depend> <build_export_depend>rospy</build_export_depend> <build_export_depend>sensor_msgs</build_export_depend> <build_export_depend>std_msgs</build_export_depend> <build_export_depend>tf</build_export_depend> <exec_depend>cv_bridge</exec_depend> <exec_depend>rospy</exec_depend> <exec_depend>sensor_msgs</exec_depend> <exec_depend>std_msgs</exec_depend> <exec_depend>tf</exec_depend> <!-- The export tag contains other, unspecified, tags --> <export> <!-- Other tools can request additional information be placed here --> </export> </package> 这是我的一个package.xml 里面的东西，你要不把你的package.xml文件发出来我看看？？
