roslib.manifest wrong

[syp1997]

When I Execute build_ros.sh, the error like this. How can I solve this problem? Thanks very much!

[rosbuild] Building package ORB_SLAM2 [rosbuild] Error from syntax check of ORB_SLAM2/manifest.xml Traceback (most recent call last): File "", line 1, in ImportError: No module named roslib.manifest CMake Error at /opt/ros/indigo/share/ros/core/rosbuild/private.cmake:78 (message): [rosbuild] Syntax check of ORB_SLAM2/manifest.xml failed; aborting Call Stack (most recent call first): /opt/ros/indigo/share/ros/core/rosbuild/public.cmake:174 (_rosbuild_check_manifest) CMakeLists.txt:4 (rosbuild_init)

hello buddy, I meet the same problem too, have your fixed it yet?

Hello everyone, I have the same problem too. Is there a solution?

I had the same problem. Somehow roslib couldn't be found even after all the environment variables were set properly. (rospack find roslib). This is a core ROS package so as a lazy solution I just reinstalled ROS and everything started to build properly.

Hi, have you resolve this error?

I fond that I can import roslib in the terminal, so I find the python interpreter. Then you need to go to this file /opt/ros/noetic/share/ros/core/rosbuild/private.cmake, about line 67 COMMAND ${PYTHON_EXECUTABLE} -c "import roslib.manifest; roslib.manifest.parse_file('manifest.xml')", just change ${PYTHON_EXECUTABLE} with /usr/bin/python3.8, then it may work.

我在编译DS_SLAM时，也遇到了同样的问题。重装了ROS，没有用。按照楼上修改了private.cmake，也不行。系统为Ubuntu20.04。

private.cmake

请问您解决这个问题了吗

它的问题是python要导入的包找不到，这个包是在roslib文件夹下的manifest.py文件。所以只需要在.bashrc文件中添加环境变量PYTHONPATH="${PYTHONPATH}:/opt/ros/noetic/lib/python3/dist-packages" export PYTHONPATH 即可（我的ROS版本是noetic）。

需要按安装位置改动dist_packages路径
