1、有博客说是rosdep的问题， 就更新了rosdep,
rosdep update
又出现新的问题：
ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.
解决新问题方法：修改host文件，参考https://community.bwbot.org/topic/811/
4.23更新：让turtlebot3建图并导航
turtlebot3教程 :https://www.ncnynl.com/archives/201702/1396.html
一、远程连接步骤
1、连上同一个无线局域网
2、pc端： ifconfig查看ip,修改bashrc文件的ip
ifconfig
gedit ~/.bashrc
source ~/.bsahrc
3、pc端： 连接机器人
SSH登录到远程计算机：$ ssh username@ip_address
ssh [email protected]
启动机器人：
export TURTLEBOT3_MODEL=burger
cd ~/catkin_ws
source devel/setup.bash
roslaunch turtlebot3_bringup turtlebot3_robot.launch
修改ip(i 编辑 esc退出编辑 shift：wq 保存退出)
vi ~/.bashrc
source ~/.bashrc
4、pc端运行以下命令才能进行节点其他操作：
cd ~/catkin_ws
source devel/setup.bash
二、运行以下启动命令时报错
ModuleNotFoundError: No module named 'rospkg'
roslaunch turtlebot3_bringup turtlebot3_robot.launch
解决方法：
1、命令行输入Python，检查Python版本是否为2.7，如果不是2.7则需要修改系统Python版本
2、确认2.7版本，命令行输入 pip install rospkg 即可
4.20更新
turtlebot3 安装软件git clone 报错（因为家里网不行）：fatal:early EOF fatal:index-pack failed
解决方法:
1、增加缓存（亲测无效）
2、直接复制github网址，下载包到catkin_ws文件夹下，再重新执行命令即可
