2. ROS 解决catkin_make时 Invoking “make -j4 -l4” failed0

问题描述如下：

Traceback (most recent call last):
  File "bin/ros1_bridge_generate_factories", line 11, in <module>
    from ros1_bridge import generate_cpp
  File "/home/ros/ros2_ws/src/ros2/ros1_bridge/ros1_bridge/__init__.py", line 13, in <module>
    import genmsg
ImportError: No module named 'genmsg'

stackflow大神给出了解释：


解决方法：

export PYTHONPATH=/opt/ros/kinetic/lib/python2.7/dist-packages/

3. ImportError: No module named em


python -m pip install empy


解决

4. Linux Conda找不到命令问题修复

修改环境变量

vim ~/.bashrc

在最后添加：

export PATH=~/anaconda3/bin:$PATH

重启环境变量：

source ~/.bashrc

5 Malformed entry 1 in list file /etc/apt/sources.list.d/ros-latest.list (Component

E: The list of sources could not be read.

ros-latest.list content:-

deb http://packages.ros.org/ros/ubuntu  main

查看

lsb_release -sc

在终端输入

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

成功搞定！！！
