这个错误可能是由于以下原因之一导致的:
1. 您的网络连接不稳定或中断,因此无法从GitHub下载所需的文件。请检查您的网络连接并再次尝试。
2. 您已经有一个名为“src”的文件夹,但其中已经存在某些文件或文件夹,这些文件或文件夹可能与您要合并的文件冲突。请先备份您的“src”文件夹,然后将它删除,再执行此命令。
3. 您的wstool工具可能已经过时或损坏。请尝试更新wstool工具或重新安装ROS,然后再次尝试执行命令。
请检查以上原因,并根据需要采取相应的措施来解决此问题。

如何安装ROS Melodic的Cartographer?
安装步骤见官方文档:https://google-cartographer-ros.readthedocs.io/en/latest/
简单来说,需要安装Cartographer和Cartographer ROS:
1. 首先安装Cartographer:
```
sudo apt-get update
sudo apt-get install -y python-wstool python-rosdep ninja-build
mkdir catkin_ws
cd catkin_ws
wstool init src
wstool merge -t src https://raw.githubusercontent.com/googlecartographer/cartographer_ros/master/cartographer_ros.rosinstall
wstool update -t src
src/cartographer/scripts/install_abseil.sh
src/cartographer/scripts/install_proto3.sh
sudo rosdep init
rosdep update
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
sudo pip install packaging
catkin_make_isolated --install --use-ninja
```
2. 安装Cartographer ROS:
```
sudo apt-get update
sudo apt-get install -y python-wstool python-rosdep ninja-build
mkdir catkin_ws
cd catkin_ws
wstool init src
wstool merge -t src https://raw.githubusercontent.com/googlecartographer/cartographer_ros/master/cartographer_ros.rosinstall
wstool update -t src
src/cartographer/scripts/install_abseil.sh
src/cartographer/scripts/install_proto3.sh
sudo rosdep init
rosdep update
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
sudo pip install packaging
catkin_make_isolated --install --use-ninja
```
二进制安装cartographer ros
要在ROS系统中安装Cartographer,可以使用以下命令:
1. 首先添加Cartographer的APT存储库:
```
sudo apt-get install -y curl gnupg2 lsb-release
curl -L https://google-cartographer-ros.s3.amazonaws.com/cartographer_ros.key | sudo apt-key add -
sudo sh -c 'echo "deb https://google-cartographer-ros.s3.amazonaws.com/$(lsb_release -sc) main" > /etc/apt/sources.list.d/cartographer_ros.list'
sudo apt-get update
```
2. 安装Cartographer ROS软件包:
```
sudo apt-get install -y cartographer_ros
```
3. 安装Cartographer ROS的依赖项:
```
sudo apt-get install -y python-wstool python-rosdep ninja-build
sudo rosdep init
rosdep update
```
4. 构建Cartographer ROS:
```
cd ~/catkin_ws/src
wstool init
wstool merge -t . https://raw.githubusercontent.com/googlecartographer/cartographer_ros/master/cartographer_ros.rosinstall
wstool update -t .
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y
catkin_make_isolated --install --use-ninja
```
其中,`~/catkin_ws/src`是你的ROS工作空间的源代码目录,`${ROS_DISTRO}`是你所使用的ROS发行版。
完成上述步骤后,就可以在ROS系统中使用Cartographer了。
