与Python兼容问题(No module catkin_dkg.package)
解决办法
检查一下Python的版本： wgb@wgb:~$ python -V
检查一下catkin依赖的Python版本： wgb@wgb:~$ dpkg -L python-catkin-pkg
如果Python的版本和catkin依赖的版本不一样，说明Python依赖包有问题，解决办法：

conda install setuptools
pip install -U rosdep rosinstall_generator wstool rosinstall six vcstools

安装canda

pip install conda

遇到问题：

解决办法：

pip install wheel
pip install --upgrade setuptools
pip install pycosat

pip install conda

若不行，
https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/?C=M&O=D
下载相应版本Anaconda3

chmod 777 xxx.sh #给执行权限
bash xxx.sh#安装
source ~/.bashrc
然后
conda install setuptools
pip install -U rosdep rosinstall_generator wstool rosinstall six vcstools
