问错误:在构建-j8 (ROS工作区)时“调用”"make -l8“失败

EN

我是ROS和模拟程序的新手。我正在尝试构建ROS工作区。

-Specifications：

• OS-Ubuntu18.04 LTS，ROS-旋律

我的目标是成功地安装erp-42的模拟。下面是我之前输入的代码。

sudo apt install ros-melodic-serial ros-melodic-velodyne-* ros-melodic-pcl-* ros-melodic-geodesy ros-melodic-ros-control ros-melodic-map-server ros-melodic-move-base ros-melodic-twist-keyboard
sudo apt install python-pip
pip install keyboard Sphinx


mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
git clone https://github.com/jdj2261/ERP42-ROS.git
cd ~/catkin_ws
rosdep install --from-paths src --ignore-src -r -y
catkin_make

以下是错误代码。

谁能帮我找出这些错误的原因吗？提前谢谢你
