ubuntu20.04-ROSNoetic装ORB-SLAM2执行./build_ros.sh时报错

-- Configuring incomplete, errors occurred!
See also "/home/sunhaochen/catkin_ws/src/ORB_SLAM2/Examples/ROS/ORB_SLAM2/build/CMakeFiles/CMakeOutput.log".
make: *** 没有指明目标并且找不到 makefile。停止。

2023年了... 有大佬解决了这个问题了吗？

上边是这些提示：

import rospkg
ImportError: No module named rospkg
CMake Error at /opt/ros/noetic/share/ros/core/rosbuild/private.cmake:77 (message)

import rospkg
ImportError: No module named rospkg

Call Stack (most recent call first):

CMakeLists.txt:4 (rosbuild_init)

请问有人解决了吗，我搞了两天了

大佬们这个问题解决了吗，我遇到了一摸一样的问题，直接用python import rospkg是不报错的

会不会是你安装了 Ros Melodic后，没有创建ROS空间。

rospkg没有安装，我在这卡了好几天，用下面的方法解决的

修改下python软连接就可以了
cd /usr/bin
sudo rm python
sudo ln -s /usr/bin/python3.x python
