bash - ROS 动力学中的豺狼模拟 - 得到错误：bash：cd：jackal_ws：没有这样的文件或目录

Question

我正在尝试按照本教程通过 Gazebo 上的 ROS Kinetic 模拟豺狼，https://gist.github.com/vfdev-5/57a0171d8f5697831dc8d374839bca12

我已完成以下步骤：

sudo apt-get install ros-kinetic-robot-localization ros-kinetic-controller-manager ros-kinetic-joint-state-controller ros-kinetic-diff-drive-controller ros-kinetic-gazebo-ros ros-kinetic-gazebo-ros-control ros-kinetic-gazebo-plugins             ros-kinetic-lms1xx ros-kinetic-pointgrey-camera-description ros-kinetic-roslint ros-kinetic-amcl ros-kinetic-gmapping      ros-kinetic-map-server ros-kinetic-move-base ros-kinetic-urdf ros-kinetic-xacro ros-kinetic-message-runtime ros-kinetic-topic-tools ros-kinetic-teleop-twist-joy    

和

mkdir -p jackal_ws/src; cd jackal_ws/src; catkin_init_workspace
git clone https://github.com/jackal/jackal.git
git clone https://github.com/jackal/jackal_simulator.git
git clone https://github.com/jackal/jackal_desktop.git
git clone https://github.com/ros-visualization/interactive_marker_twist_server.git

经过上述步骤，我得到：

bash: cd: jackal_ws: No such file or directory

然后，我做了下面的下一步：

cd jackal_ws; catkin_make; source devel/setup.bash

经过上述步骤，我得到：

bash: cd: jackal_ws: No such file or directory  
Base path: /home/USER/jackal_ws/src  
The specified source space "/home/USER/jackal_ws/src/src" does not exist   
bash: devel/setup.bash: No such file or directory

我做错了什么？

我分别重做了这些步骤，这是我在终端中得到的：
