找不到Catkin命令

Question

我在Ubuntu 14.04.5中安装了ROS indigo和gazebo2软件包.当我尝试使用catkin命令时,我得到:

catkin_init_workspace:找不到命令

所以,我试图安装catkin,它显示ros-indigo-catkin是最新版本.

我所做的只是,

$ sudo apt-get install ros-indigo-desktop-full

$ sudo apt-get install gazebo2.<They're installed perfectly>

在此之后,我遇到了问题.

需要帮助.有人请找到解决此问题的方法.

Answer 1

如果工作区已设置，您已按照上述方式正确获取了 ROS，如果 catkin_make 有效，但 catkin build 不起作用，请执行以下操作：

sudo apt install python3-catkin-tools python3-osrf-pycommon

这是一个catkin-tools依赖项，在Ubuntu 20.04中被取消链接，因此必须手动指定才能安装。

安装ROS后可能忘了设置环境.

$ echo "source /opt/ros/indigo/setup.bash" >> ~/.bashrc
$ source ~/.bashrc

然后,我假设您要创建一个包,因此您可以按照以下步骤操作:

$ mkdir -p path_to_my_workspace/workspace_name/src
$ cd path_to_my_workspace/workspace_name/src
$ catkin_init_workspace
$ cd path_to_my_workspace/workspace_name/
$ catkin_make
$ source path_to_my_workspace/workspace_name/devel/setup.bash

运行这些命令后,将创建工作区,现在您可以开始添加包.
