ROS catkin_make：rebuild package（s）

Question

我发现我错误地将依赖项“std_msgs”命名为“std_msg”。 所以我定！但等待，柳絮仍然认为lawnbot_description是要“std_msg”作为一个依赖，即使我固定的依赖性：

：

<?xml version="1.0"?> 
<package format="2"> 
    <name>lawnbot_description</name> 
    <version>0.0.0</version> 
    <description>The lawnbot_description package</description>  

    <buildtool_depend>catkin</buildtool_depend> 
    <build_depend>roscpp</build_depend> 
    <build_depend>rospy</build_depend> 
    <build_depend>std_msgs</build_depend> 
    <build_export_depend>roscpp</build_export_depend> 
    <build_export_depend>rospy</build_export_depend> 
    <build_export_depend>std_msgs</build_export_depend> 
    <exec_depend>roscpp</exec_depend> 
    <exec_depend>rospy</exec_depend> 
    <exec_depend>std_msgs</exec_depend> 

做catkin_make --force-cmake的错误时，输出

它仍然认为lawnbot_description包想要“std_msg”。为什么这么难？修改软件包信息并对其进行更新并不容易。

我发现有一个名为catkin_tools clean的包，但为什么我需要下载一个额外的包来简单地更新我的工作区？

我曾尝试：

-catkin_make 
-catkin_make --force-cmake 
- I have seen solutions that involve deleting entire build/devel directories which horrifies me. That seems like a ton of work just to add an 's' to the end of a name 

我很担心，柳絮干净lawnbot_description只会删除整个包。这是我最好的选择吗？

本地lawnbot_description cmake的文件：

cmake_minimum_required(VERSION 2.8.3) 
project(lawnbot_description) 

find_package(catkin REQUIRED COMPONENTS 
    roscpp 
    rospy 
    std_msg # I am not supposed to edit this right??? I tried editing and it still does not work 
) 

Answer 1

我发现，编辑CMakeLists解决了这个问题。然而令人讨厌的是，我需要更改package.xml和CMakeLists以指示依赖关系的更改。

我认为如果我修复package.xml，CMakeLists会被更新。

所以将来的参考，请编辑包中的CMakeLists以反映对包所做的更改。 catkin_make不会为你这样做。

find_package(catkin REQUIRED COMPONENTS 
    roscpp 
    rospy 
    std_msg 
) 

应该是：

find_package(catkin REQUIRED COMPONENTS 
    roscpp 
    rospy 
    std_msgs 
) 

随着更新package.xml中
